+
+ <h1><a name="1">1 Introduction</a></h1>
+
+ <p>C++/Tree is a W3C XML Schema to C++ mapping that represents the
+ data stored in XML as a statically-typed, vocabulary-specific
+ object model. Based on a formal description of an XML vocabulary
+ (schema), the C++/Tree mapping produces a tree-like data structure
+ suitable for in-memory processing as well as XML parsing and
+ serialization code.</p>
+
+ <p>A typical application that processes XML documents usually
+ performs the following three steps: it first reads (parses) an XML
+ instance document to an object model, it then performs
+ some useful computations on that model which may involve
+ modification of the model, and finally it may write (serialize)
+ the modified object model back to XML.
+ </p>
+
+ <p>The C++/Tree mapping consists of C++ types that represent the
+ given vocabulary (<a href="#2">Chapter 2, "C++/Tree Mapping"</a>),
+ a set of parsing functions that convert XML documents to
+ a tree-like in-memory data structure (<a href="#3">Chapter 3,
+ "Parsing"</a>), and a set of serialization functions that convert
+ the object model back to XML (<a href="#4">Chapter 4,
+ "Serialization"</a>). Furthermore, the mapping provides a number
+ of additional features, such as DOM association and binary
+ serialization, that can be useful in some applications
+ (<a href="#5">Chapter 5, "Additional Functionality"</a>).
+ </p>

+ <h1><a name="2">2 C++/Tree Mapping</a></h1>
+
+ <h2><a name="2.1">2.1 Preliminary Information</a></h2>
+
+ <h3><a name="2.1.1">2.1.1 Identifiers</a></h3>
+
+ <p>XML Schema names may happen to be reserved C++ keywords or contain
+ characters that are illegal in C++ identifiers. To avoid C++ compilation
+ problems, such names are changed (escaped) when mapped to C++. If an
+ XML Schema name is a C++ keyword, the "_" suffix is added to it. All
+ character of an XML Schema name that are not allowed in C++ identifiers
+ are replaced with "_".
+ </p>
+
+ <p>For example, XML Schema name <code>try</code> will be mapped to
+ C++ identifier <code>try_</code>. Similarly, XML Schema name
+ <code>strange.na-me</code> will be mapped to C++ identifier
+ <code>strange_na_me</code>.
+ </p>
+
+ <p>Furthermore, conflicts between type names and function names in the
+ same scope are resolved using name escaping. Such conflicts include
+ both a global element (which is mapped to a set of parsing and/or
+ serialization functions or element types, see <a href="#2.9">Section
+ 2.9, "Mapping for Global Elements"</a>) and a global type sharing the
+ same name as well as a local element or attribute inside a type having
+ the same name as the type itself.</p>
+
+ <p>For example, if we had a global type <code>catalog</code>
+ and a global element with the same name then the type would be
+ mapped to a C++ class with name <code>catalog</code> while the
+ parsing functions corresponding to the global element would have
+ their names escaped as <code>catalog_</code>.
+ </p>
+
+ <p>By default the mapping uses the so-called K&amp;R (Kernighan and
+ Ritchie) identifier naming convention which is also used throughout
+ this manual. In this convention both type and function names are in
+ lower case and words are separated by underscores. If your application
+ code or schemas use a different notation, you may want to change the
+ naming convention used by the mapping for consistency.
+ The compiler supports a set of widely-used naming conventions
+ that you can select with the <code>--type-naming</code> and
+ <code>--function-naming</code> options. You can also further
+ refine one of the predefined conventions or create a completely
+ custom naming scheme by using the <code>--*-regex</code> options.
+ For more detailed information on these options refer to the NAMING
+ CONVENTION section in the <a href="http://www.codesynthesis.com/projects/xsd/documentation/xsd.xhtml">XSD
+ Compiler Command Line Manual</a>.</p>
+
+ <h3><a name="2.1.2">2.1.2 Character Type and Encoding</a></h3>
+
+ <p>The code that implements the mapping, depending on the
+ <code>--char-type</code> option, is generated using either
+ <code>char</code> or <code>wchar_t</code> as the character
+ type. In this document code samples use symbol <code>C</code>
+ to refer to the character type you have selected when translating
+ your schemas, for example <code>std::basic_string&lt;C></code>.
+ </p>
+
+ <p>Another aspect of the mapping that depends on the character type
+ is character encoding. For the <code>char</code> character type
+ the default encoding is UTF-8. Other supported encodings are
+ ISO-8859-1, Xerces-C++ Local Code Page (LPC), as well as
+ custom encodings and can be selected with the
+ <code>--char-encoding</code> command line option.</p>
+
+ <p>For the <code>wchar_t</code> character type the encoding is
+ automatically selected between UTF-16 and UTF-32/UCS-4 depending
+ on the size of the <code>wchar_t</code> type. On some platforms
+ (for example, Windows with Visual C++ and AIX with IBM XL C++)
+ <code>wchar_t</code> is 2 bytes long. For these platforms the
+ encoding is UTF-16. On other platforms <code>wchar_t</code> is 4 bytes
+ long and UTF-32/UCS-4 is used.</p>
+
+ <h3><a name="2.1.3">2.1.3 XML Schema Namespace</a></h3>
+
+ <p>The mapping relies on some predefined types, classes, and functions
+ that are logically defined in the XML Schema namespace reserved for
+ the XML Schema language (<code>http://www.w3.org/2001/XMLSchema</code>).
+ By default, this namespace is mapped to C++ namespace
+ <code>xml_schema</code>. It is automatically accessible
+ from a C++ compilation unit that includes a header file generated
+ from an XML Schema definition.
+ </p>
+
+ <p>Note that, if desired, the default mapping of this namespace can be
+ changed as described in <a href="#2.4">Section 2.4, "Mapping for
+ Namespaces"</a>.
+ </p>
+
+
+ <h3><a name="2.1.4">2.1.4 Anonymous Types</a></h3>
+
+ <p>For the purpose of code generation, anonymous types defined in
+ XML Schema are automatically assigned names that are derived
+ from enclosing attributes and elements. Otherwise, such types
+ follows standard mapping rules for simple and complex type
+ definitions (see <a href="#2.6">Section 2.6, "Mapping for Simple Types"</a>
+ and <a href="#2.7">Section 2.7, "Mapping for Complex Types"</a>).
+ For example, in the following schema fragment:
+ </p>
+
+ <pre class="xml">
+&lt;element name="object">
+ &lt;complexType>
+ ...
+ &lt;/complexType>
+&lt;/element>
+ </pre>
+
+ <p>The anonymous type defined inside element <code>object</code> will
+ be given name <code>object</code>. The compiler has a number of
+ options that control the process of anonymous type naming. For more
+ information refer to the <a href="http://www.codesynthesis.com/projects/xsd/documentation/xsd.xhtml">XSD
+ Compiler Command Line Manual</a>.</p>
+
+
+ <h2><a name="2.2">2.2 Error Handling</a></h2>
+
+ <p>The mapping uses the C++ exception handling mechanism as a primary way
+ of reporting error conditions. All exceptions that are specified in
+ this mapping derive from <code>xml_schema::exception</code> which
+ itself is derived from <code>std::exception</code>:
+ </p>
+
+ <pre class="c++">
+struct exception: virtual std::exception
+{
+ friend
+ std::basic_ostream&lt;C>&amp;
+ operator&lt;&lt; (std::basic_ostream&lt;C>&amp; os, const exception&amp; e)
+ {
+ e.print (os);
+ return os;
+ }
+
+protected:
+ virtual void
+ print (std::basic_ostream&lt;C>&amp;) const = 0;
+};
+ </pre>
+
+ <p>The exception hierarchy supports "virtual" <code>operator&lt;&lt;</code>
+ which allows you to obtain diagnostics corresponding to the thrown
+ exception using the base exception interface. For example:</p>
+
+ <pre class="c++">
+try
+{
+ ...
+}
+catch (const xml_schema::exception&amp; e)
+{
+ cerr &lt;&lt; e &lt;&lt; endl;
+}
+ </pre>
+
+ <p>The following sub-sections describe exceptions thrown by the
+ types that constitute the object model.
+ <a href="#3.3">Section 3.3, "Error Handling"</a> of
+ <a href="#3">Chapter 3, "Parsing"</a> describes exceptions
+ and error handling mechanisms specific to the parsing functions.
+ <a href="#4.4">Section 4.4, "Error Handling"</a> of
+ <a href="#4">Chapter 4, "Serialization"</a> describes exceptions
+ and error handling mechanisms specific to the serialization functions.
+ </p>
+
+
+ <h3><a name="2.2.1">2.2.1 <code>xml_schema::duplicate_id</code></a></h3>
+
+ <pre class="c++">
+struct duplicate_id: virtual exception
+{
+ duplicate_id (const std::basic_string&lt;C>&amp; id);
+
+ const std::basic_string&lt;C>&amp;
+ id () const;
+
+ virtual const char*
+ what () const throw ();
+};
+ </pre>
+
+ <p>The <code>xml_schema::duplicate_id</code> is thrown when
+ a conflicting instance of <code>xml_schema::id</code> (see
+ <a href="#2.5">Section 2.5, "Mapping for Built-in Data Types"</a>)
+ is added to a tree. The offending ID value can be obtained using
+ the <code>id</code> function.
+ </p>
+
+ <h2><a name="2.3">2.3 Mapping for <code>import</code> and <code>include</code></a></h2>
+
+ <h3><a name="2.3.1">2.3.1 Import</a></h3>
+
+ <p>The XML Schema <code>import</code> element is mapped to the C++
+ Preprocessor <code>#include</code> directive. The value of
+ the <code>schemaLocation</code> attribute is used to derive
+ the name of the header file that appears in the <code>#include</code>
+ directive. For instance:
+ </p>
+
+ <pre class="xml">
+&lt;import namespace="http://www.codesynthesis.com/test"
+ schemaLocation="test.xsd"/>
+ </pre>
+
+ <p>is mapped to:</p>
+
+ <pre class="c++">
+#include "test.hxx"
+ </pre>
+
+ <p>Note that you will need to compile imported schemas separately
+ in order to produce corresponding header files.</p>
+
+ <h3><a name="2.3.2">2.3.2 Inclusion with Target Namespace</a></h3>
+
+ <p>The XML Schema <code>include</code> element which refers to a schema
+ with a target namespace or appears in a schema without a target namespace
+ follows the same mapping rules as the <code>import</code> element,
+ see <a href="#2.3.1">Section 2.3.1, "Import"</a>.
+ </p>
+
+ <h3><a name="2.3.3">2.3.3 Inclusion without Target Namespace</a></h3>
+
+ <p>For the XML Schema <code>include</code> element which refers to a schema
+ without a target namespace and appears in a schema with a target
+ namespace (such inclusion sometimes called "chameleon inclusion"),
+ declarations and definitions from the included schema are generated
+ in-line in the namespace of the including schema as if they were
+ declared and defined there verbatim. For example, consider the
+ following two schemas:
+ </p>
+
+ <pre class="xml">
+&lt;-- common.xsd -->
+&lt;schema>
+ &lt;complexType name="type">
+ ...
+ &lt;/complexType>
+&lt;/schema>
+
+&lt;-- test.xsd -->
+&lt;schema targetNamespace="http://www.codesynthesis.com/test">
+ &lt;include schemaLocation="common.xsd"/>
+&lt;/schema>
+ </pre>
+
+ <p>The fragment of interest from the generated header file for
+ <code>text.xsd</code> would look like this:</p>
+
+ <pre class="c++">
+// test.hxx
+namespace test
+{
+ class type
+ {
+ ...
+ };
+}
+ </pre>
+
+ <h2><a name="2.4">2.4 Mapping for Namespaces</a></h2>
+
+ <p>An XML Schema namespace is mapped to one or more nested C++
+ namespaces. XML Schema namespaces are identified by URIs.
+ By default, a namespace URI is mapped to a sequence of
+ C++ namespace names by removing the protocol and host parts
+ and splitting the rest into a sequence of names with '<code>/</code>'
+ as the name separator. For instance:
+ </p>
+
+ <pre class="xml">
+&lt;schema targetNamespace="http://www.codesynthesis.com/system/test">
+ ...
+&lt;/schema>
+ </pre>
+
+ <p>is mapped to:</p>
+
+ <pre class="c++">
+namespace system
+{
+ namespace test
+ {
+ ...
+ }
+}
+ </pre>
+
+ <p>The default mapping of namespace URIs to C++ namespace names can be
+ altered using the <code>--namespace-map</code> and
+ <code>--namespace-regex</code> options. See the
+ <a href="http://www.codesynthesis.com/projects/xsd/documentation/xsd.xhtml">XSD
+ Compiler Command Line Manual</a> for more information.
+ </p>

+ <p>All XML Schema built-in types are mapped to C++ classes that are
+ derived from the <code>xml_schema::simple_type</code> class except
+ where the mapping is to a fundamental C++ type.</p>
+
+ <p>The <code>sequence</code> class template is defined in an
+ implementation-specific namespace. It conforms to the
+ sequence interface as defined by the ISO/ANSI Standard for
+ C++ (ISO/IEC 14882:1998, Section 23.1.1, "Sequences").
+ Practically, this means that you can treat such a sequence
+ as if it was <code>std::vector</code>. One notable extension
+ to the standard interface that is available only for
+ sequences of non-fundamental C++ types is the addition of
+ the overloaded <code>push_back</code> and <code>insert</code>
+ member functions which instead of the constant reference
+ to the element type accept automatic pointer to the element
+ type. These functions assume ownership of the pointed to
+ object and resets the passed automatic pointer.
+ </p>
+
+ <h3><a name="2.5.1">2.5.1 Inheritance from Built-in Data Types</a></h3>
+
+ <p>In cases where the mapping calls for an inheritance from a built-in
+ type which is mapped to a fundamental C++ type, a proxy type is
+ used instead of the fundamental C++ type (C++ does not allow
+ inheritance from fundamental types). For instance:</p>
+
+ <pre class="xml">
+&lt;simpleType name="my_int">
+ &lt;restriction base="int"/>
+&lt;/simpleType>
+ </pre>
+
+ <p>is mapped to:</p>
+
+ <pre class="c++">
+class my_int: public fundamental_base&lt;int>
+{
+ ...
+};
+ </pre>
+
+ <p>The <code>fundamental_base</code> class template provides a close
+ emulation (though not exact) of a fundamental C++ type.
+ It is defined in an implementation-specific namespace and has the
+ following interface:</p>
+
+ <pre class="c++">
+template &lt;typename X>
+class fundamental_base: public simple_type
+{
+public:
+ fundamental_base ();
+ fundamental_base (X)
+ fundamental_base (const fundamental_base&amp;)

+ </pre>
+
+ <p>The object, <code>idref</code> instance refers to, is the immediate
+ container of the matching <code>id</code> instance. For example,
+ with the following instance document and schema:
+ </p>
+
+
+ <pre class="xml">
+&lt;!-- test.xml -->
+&lt;root>
+ &lt;object id="obj-1" text="hello"/>

+ &lt;/complexType>
+
+ &lt;element name="root" type="root_type"/>

+cout &lt;&lt; obj.text () &lt;&lt; endl;
+ </pre>
+
+ <p>The smart pointer interface of the <code>idref</code> class always
+ returns a pointer or reference to <code>xml_schema::type</code>.
+ This means that you will need to manually cast such pointer or
+ reference to its real (dynamic) type before you can use it (unless
+ all you need is the base interface provided by
+ <code>xml_schema::type</code>). As a special extension to the XML
+ Schema language, the mapping supports static typing of <code>idref</code>
+ references by employing the <code>refType</code> extension attribute.
+ The following example illustrates this mechanism:
+ </p>
+
+ <pre class="xml">
+&lt;!-- test.xsd -->
+&lt;schema
+ xmlns:xse="http://www.codesynthesis.com/xmlns/xml-schema-extension">
+

+
+ &lt;element name="reference" type="IDREF" xse:refType="object_type"/>
+
+ ...
+
+&lt;/schema>
+ </pre>
+
+ <p>With this modification we do not need to do manual casting anymore:
+ </p>
+
+ <pre class="c++">
+root_type&amp; root = ...;
+root_type::reference_type&amp; ref (root.reference ());
+object_type&amp; obj (*ref);

+ definitions in the resulting C++ class. Instead, corresponding

+
+ <!-- 2.8 Mapping for Local Elements and Attributes -->
+
+ <h2><a name="2.8">2.8 Mapping for Local Elements and Attributes</a></h2>
+
+ <p>XML Schema element and attribute definitions are called local
+ if they appear within a complex type definition, an element group
+ definition, or an attribute group definitions.
+ </p>
+
+ <p>Local XML Schema element and attribute definitions have the same
+ C++ mapping. Therefore, in this section, local elements and
+ attributes are collectively called members.
+ </p>
+
+ <p>While there are many different member cardinality combinations
+ (determined by the <code>use</code> attribute for attributes and
+ the <code>minOccurs</code> and <code>maxOccurs</code> attributes
+ for elements), the mapping divides all possible cardinality
+ combinations into three cardinality classes:
+ </p>
+
+ <dl>
+ <dt><i>one</i></dt>
+ <dd>attributes: <code>use == "required"</code></dd>
+ <dd>attributes: <code>use == "optional"</code> and has default or fixed value</dd>
+ <dd>elements: <code>minOccurs == "1"</code> and <code>maxOccurs == "1"</code></dd>
+
+ <dt><i>optional</i></dt>
+ <dd>attributes: <code>use == "optional"</code> and doesn't have default or fixed value</dd>
+ <dd>elements: <code>minOccurs == "0"</code> and <code>maxOccurs == "1"</code></dd>
+
+ <dt><i>sequence</i></dt>
+ <dd>elements: <code>maxOccurs > "1"</code></dd>
+ </dl>
+
+ <p>An optional attribute with a default or fixed value acquires this value
+ if the attribute hasn't been specified in an instance document (see
+ <a href="#A">Appendix A, "Default and Fixed Values"</a>). This
+ mapping places such optional attributes to the One cardinality
+ class.</p>
+
+ <p>A member is mapped to a set of public type definitions
+ (<code>typedef</code>s) and a set of public accessor and modifier
+ functions. Type definitions have names derived from the member's
+ name. The accessor and modifier functions have the same name as the
+ member. For example:
+ </p>
+
+ <pre class="xml">
+&lt;complexType name="object">
+ &lt;sequence>
+ &lt;element name="member" type="string"/>
+ &lt;/sequence>
+&lt;/complexType>

+{
+public:
+ typedef xml_schema::string member_type;
+
+ const member_type&amp;
+ member () const;
+
+ ...
+
+};
+ </pre>
+
+ <p>In addition, if a member has a default or fixed value, a static
+ accessor function is generated that returns this value. For
+ example:</p>
+
+<pre class="xml">
+&lt;complexType name="object">
+ &lt;attribute name="data" type="string" default="test"/>

+ Practically, this means that you can treat such a sequence

+ <h2><a name="2.9">2.9 Mapping for Global Elements</a></h2>
+
+ <p>An XML Schema element definition is called global if it appears
+ directly under the <code>schema</code> element.
+ A global element is a valid root of an instance document. By
+ default, a global element is mapped to a set of overloaded
+ parsing and, optionally, serialization functions with the
+ same name as the element. It is also possible to generate types
+ for root elements instead of parsing and serialization functions.
+ This is primarily useful to distinguish object models with the
+ same root type but with different root elements. See
+ <a href="#2.9.1">Section 2.9.1, "Element Types"</a> for details.
+ It is also possible to request the generation of an element map
+ which allows uniform parsing and serialization of multiple root
+ elements. See <a href="#2.9.2">Section 2.9.2, "Element Map"</a>
+ for details.
+ </p>
+
+ <p>The parsing functions read XML instance documents and return
+ corresponding object models. Their signatures
+ have the following pattern (<code>type</code> denotes
+ element's type and <code>name</code> denotes element's
+ name):
+ </p>
+
+ <pre class="c++">
+std::auto_ptr&lt;type>
+name (....);

+
+ <p>The process of parsing, including the exact signatures of the parsing
+ functions, is the subject of <a href="#3">Chapter 3, "Parsing"</a>.
+ </p>
+
+ <p>The serialization functions write object models

+
+ <pre class="c++">
+void
+name (&lt;stream type>&amp;, const type&amp;, ....);

+
+ <p>The generation of element types is requested with the

+ of type definitions, constructors, and member function as would a
+ type containing a single element with the One cardinality class
+ named <code>"value"</code>. In addition, the element type also

+
+
+ <h3><a name="2.9.2">2.9.2 Element Map</a></h3>
+
+ <p>When element types are generated for root elements it is also

+
+ <pre class="c++">

+ };
+}
+ </pre>
+
+ <p>The <code>parse()</code> function creates the corresponding
+ element type object based on the element name and namespace
+ and returns it as a pointer to <code>xml_schema::element_type</code>.
+ The <code>serialize()</code> function serializes the passed element
+ object to <code>DOMElement</code>. Note that in case of
+ <code>serialize()</code>, the <code>DOMElement</code> object
+ should have the correct name and namespace. If no element type is
+ available for an element, both functions throw the
+ <code>xml_schema::no_element_info</code> exception:</p>
+
+ <pre class="c++">
+struct no_element_info: virtual exception
+{

+
+ <p>The application can discover the actual type of the element

+&lt;/root>
+ </pre>
+
+ <p>In the resulting object model, the container for
+ the <code>root::item</code> member will have two elements:
+ the first element's type will be <code>base</code> while
+ the second element's (dynamic) type will be
+ <code>derived</code>. This can be discovered using the
+ <code>dynamic_cast</code> operator as shown in the following
+ example:
+ </p>
+
+ <pre class="c++">
+void
+f (root&amp; r)
+{
+ for (root::item_const_iterator i (r.item ().begin ());
+ i != r.item ().end ()

+ {
+ // derived
+ }
+ else
+ {
+ // base
+ }
+ }
+}
+ </pre>
+
+ <p>The <code>_clone</code> virtual function should be used instead of
+ copy constructors to make copies of members that might use
+ polymorphism:
+ </p>
+
+ <pre class="c++">
+void
+f (root&amp; r)
+{

+ i != r.item ().end ()
+ ++i)
+ {
+ std::auto_ptr&lt;base> c (i->_clone ());
+ }
+}
+ </pre>
+
+ <p>The mapping can often automatically determine which types are
+ polymorphic based on the substitution group declarations. However,
+ if your XML vocabulary is not using substitution groups or if
+ substitution groups are defined in a separate schema, then you will
+ need to use the <code>--polymorphic-type</code> option to specify
+ which types are polymorphic. When using this option you only need
+ to specify the root of a polymorphic type hierarchy and the mapping
+ will assume that all the derived types are also polymorphic.
+ Also note that you need to specify this option when compiling every
+ schema file that references the polymorphic type. Consider the following
+ two schemas as an example:</p>
+
+ <pre class="xml">
+&lt;!-- base.xsd -->
+&lt;xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

+
+ <h2><a name="2.12">2.12 Mapping for <code>any</code> and <code>anyAttribute</code></a></h2>
+
+ <p>For the XML Schema <code>any</code> and <code>anyAttribute</code>
+ wildcards an optional mapping can be requested with the
+ <code>--generate-wildcard</code> option. The mapping represents
+ the content matched by wildcards as DOM fragments. Because the
+ DOM API is used to access such content, the Xerces-C++ runtime
+ should be initialized by the application prior to parsing and
+ should remain initialized for the lifetime of objects with
+ the wildcard content. For more information on the Xerces-C++
+ runtime initialization see <a href="#3.1">Section 3.1,
+ "Initializing the Xerces-C++ Runtime"</a>.
+ </p>
+
+ <p>The mapping for <code>any</code> is similar to the mapping for
+ local elements (see <a href="#2.8">Section 2.8, "Mapping for Local
+ Elements and Attributes"</a>) except that the type used in the
+ wildcard mapping is <code>xercesc::DOMElement</code>. As with local
+ elements, the mapping divides all possible cardinality combinations
+ into three cardinality classes: <i>one</i>, <i>optional</i>, and
+ <i>sequence</i>.
+ </p>
+
+ <p>The mapping for <code>anyAttribute</code> represents the attributes
+ matched by this wildcard as a set of <code>xercesc::DOMAttr</code>
+ objects with a key being the attribute's name and namespace.</p>
+
+ <p>Similar to local elements and attributes, the <code>any</code> and
+ <code>anyAttribute</code> wildcards are mapped to a set of public type
+ definitions (typedefs) and a set of public accessor and modifier
+ functions. Type definitions have names derived from <code>"any"</code>
+ for the <code>any</code> wildcard and <code>"any_attribute"</code>
+ for the <code>anyAttribute</code> wildcard. The accessor and modifier
+ functions are named <code>"any"</code> for the <code>any</code> wildcard
+ and <code>"any_attribute"</code> for the <code>anyAttribute</code>
+ wildcard. Subsequent wildcards in the same type have escaped names
+ such as <code>"any1"</code> or <code>"any_attribute1"</code>.
+ </p>
+
+ <p>Because Xerces-C++ DOM nodes always belong to a <code>DOMDocument</code>,
+ each type with a wildcard has an associated <code>DOMDocument</code>
+ object. The reference to this object can be obtained using the accessor
+ function called <code>dom_document</code>. The access to the document
+ object from the application code may be necessary to create or modify
+ the wildcard content. For example:
+ </p>
+
+ <pre class="xml">
+&lt;complexType name="object">
+ &lt;sequence>
+ &lt;any namespace="##other"/>
+ &lt;/sequence>
+ &lt;anyAttribute namespace="##other"/>
+&lt;/complexType>
+ </pre>
+
+ <p>is mapped to:</p>
+
+ <pre class="c++">
+class object: xml_schema::type

+ const xercesc::DOMDocument&amp;

+
+ xercesc::DOMDocument&amp;
+ dom_document ();
+
+ ...
+};
+ </pre>
+
+
+ <p>Names and semantics of type definitions for the wildcards as well
+ as signatures of the accessor and modifier functions depend on the
+ wildcard type as well as the cardinality class for the <code>any</code>
+ wildcard. They are described in the following sub-sections.
+ </p>
+
+
+ <h3><a name="2.12.1">2.12.1 Mapping for <code>any</code> with the One Cardinality Class</a></h3>
+
+ <p>For <code>any</code> with the One cardinality class,
+ there are no type definitions. The accessor functions come in
+ constant and non-constant versions. The constant accessor function
+ returns a constant reference to <code>xercesc::DOMElement</code> and
+ can be used for read-only access. The non-constant version returns
+ an unrestricted reference to <code>xercesc::DOMElement</code> and can
+ be used for read-write access.
+ </p>
+
+ <p>The first modifier function expects an argument of type reference
+ to constant <code>xercesc::DOMElement</code> and makes a deep copy
+ of its argument. The second modifier function expects an argument of
+ type pointer to <code>xercesc::DOMElement</code>. This modifier
+ function assumes ownership of its argument and expects the element
+ object to be created using the DOM document associated with this
+ instance. For example:
+ </p>
+
+ <pre class="xml">
+&lt;complexType name="object">
+ &lt;sequence>
+ &lt;any namespace="##other"/>
+ &lt;/sequence>

+
+ <h3><a name="2.12.2">2.12.2 Mapping for <code>any</code> with the Optional Cardinality Class</a></h3>
+
+ <p>For <code>any</code> with the Optional cardinality class, the type
+ definitions consist of an alias for the container type with name
+ <code>any_optional</code> (or <code>any1_optional</code>, etc., for
+ subsequent wildcards in the type definition).
+ </p>
+
+ <p>Unlike accessor functions for the One cardinality class, accessor
+ functions for the Optional cardinality class return references to
+ corresponding containers rather than directly to <code>DOMElement</code>.
+ The accessor functions come in constant and non-constant versions.
+ The constant accessor function returns a constant reference to
+ the container and can be used for read-only access. The non-constant
+ version returns an unrestricted reference to the container
+ and can be used for read-write access.
+ </p>
+
+ <p>The modifier functions are overloaded for <code>xercesc::DOMElement</code>
+ and the container type. The first modifier function expects an argument of
+ type reference to constant <code>xercesc::DOMElement</code> and
+ makes a deep copy of its argument. The second modifier function
+ expects an argument of type pointer to <code>xercesc::DOMElement</code>.
+ This modifier function assumes ownership of its argument and expects
+ the element object to be created using the DOM document associated
+ with this instance. The third modifier function expects an argument
+ of type reference to constant of the container type and makes a
+ deep copy of its argument. For instance:
+ </p>

+ <p>You can choose between reading an XML instance from a local file,
+ URI, <code>std::istream</code>, <code>xercesc::InputSource</code>,
+ or a pre-parsed DOM instance in the form of
+ <code>xercesc::DOMDocument</code>. Each of these parsing functions
+ is discussed in more detail in the following sections.
+ </p>
+
+ <h2><a name="3.1">3.1 Initializing the Xerces-C++ Runtime</a></h2>
+
+ <p>Some parsing functions expect you to initialize the Xerces-C++
+ runtime while others initialize and terminate it as part of their
+ work. The general rule is as follows: if a function has any arguments
+ or return a value that is an instance of a Xerces-C++ type, then
+ this function expects you to initialize the Xerces-C++ runtime.
+ Otherwise, the function initializes and terminates the runtime for
+ you. Note that it is legal to have nested calls to the Xerces-C++
+ initialize and terminate functions as long as the calls are balanced.
+ </p>
+
+ <p>You can instruct parsing functions that initialize and terminate
+ the runtime not to do so by passing the
+ <code>xml_schema::flags::dont_initialize</code> flag (see
+ <a href="#3.2">Section 3.2, "Flags and Properties"</a>).
+ </p>
+
+
+ <h2><a name="3.2">3.2 Flags and Properties</a></h2>
+
+ <p>Parsing flags and properties are the last two arguments of every
+ parsing function. They allow you to fine-tune the process of
+ instance validation and parsing. Both arguments are optional.
+ </p>
+
+
+ <p>The following flags are recognized by the parsing functions:</p>
+
+ <dl>
+ <dt><code>xml_schema::flags::keep_dom</code></dt>
+ <dd>Keep association between DOM nodes and the resulting
+ object model nodes. For more information about DOM association
+ refer to <a href="#5.1">Section 5.1, "DOM Association"</a>.</dd>
+
+ <dt><code>xml_schema::flags::own_dom</code></dt>
+ <dd>Assume ownership of the DOM document passed. This flag only
+ makes sense together with the <code>keep_dom</code> flag in
+ the call to the parsing function with the
+ <code>xml_schema::dom::auto_ptr&lt;DOMDocument></code>
+ argument.</dd>
+
+ <dt><code>xml_schema::flags::dont_validate</code></dt>
+ <dd>Do not validate instance documents against schemas.</dd>
+
+ <dt><code>xml_schema::flags::dont_initialize</code></dt>
+ <dd>Do not initialize the Xerces-C++ runtime.</dd>
+ </dl>
+
+ <p>You can pass several flags by combining them using the bit-wise OR
+ operator. For example:</p>
+
+ <pre class="c++">
+using xml_schema::flags;
+
+std::auto_ptr&lt;type> r (
+ name ("test.xml", flags::keep_dom | flags::dont_validate));
+ </pre>
+
+ <p>By default, validation of instance documents is turned on even
+ though parsers generated by XSD do not assume instance
+ documents are valid. They include a number of checks that prevent
+ construction of inconsistent object models. This,
+ however, does not mean that an instance document that was
+ successfully parsed by the XSD-generated parsers is
+ valid per the corresponding schema. If an instance document is not
+ "valid enough" for the generated parsers to construct consistent
+ object model, one of the exceptions defined in
+ <code>xml_schema</code> namespace is thrown (see
+ <a href="#3.3">Section 3.3, "Error Handling"</a>).
+ </p>
+
+ <p>For more information on the Xerces-C++ runtime initialization
+ refer to <a href="#3.1">Section 3.1, "Initializing the Xerces-C++
+ Runtime"</a>.
+ </p>
+
+ <p>The <code>xml_schema::properties</code> class allows you to
+ programmatically specify schema locations to be used instead
+ of those specified with the <code>xsi::schemaLocation</code>
+ and <code>xsi::noNamespaceSchemaLocation</code> attributes
+ in instance documents. The interface of the <code>properties</code>
+ class is presented below:
+ </p>
+
+ <pre class="c++">
+class properties
+{
+public:
+ void
+ schema_location (const std::basic_string&lt;C>&amp; namespace_,
+ const std::basic_string&lt;C>&amp; location);
+ void
+ no_namespace_schema_location (const std::basic_string&lt;C>&amp; location);
+};
+ </pre>
+
+ <p>Note that all locations are relative to an instance document unless
+ they are URIs. For example, if you want to use a local file as your
+ schema, then you will need to pass
+ <code>file:///absolute/path/to/your/schema</code> as the location
+ argument.
+ </p>
+
+ <h2><a name="3.3">3.3 Error Handling</a></h2>
+
+ <p>As discussed in <a href="#2.2">Section 2.2, "Error Handling"</a>,
+ the mapping uses the C++ exception handling mechanism as its primary
+ way of reporting error conditions. However, to handle recoverable
+ parsing and validation errors and warnings, a callback interface maybe
+ preferred by the application.</p>
+
+ <p>To better understand error handling and reporting strategies employed
+ by the parsing functions, it is useful to know that the
+ transformation of an XML instance document to a statically-typed
+ tree happens in two stages. The first stage, performed by Xerces-C++,
+ consists of parsing an XML document into a DOM instance. For short,
+ we will call this stage the XML-DOM stage. Validation, if not disabled,
+ happens during this stage. The second stage,
+ performed by the generated parsers, consist of parsing the DOM
+ instance into the statically-typed tree. We will call this stage
+ the DOM-Tree stage. Additional checks are performed during this
+ stage in order to prevent construction of inconsistent tree which
+ could otherwise happen when validation is disabled, for example.</p>
+
+ <p>All parsing functions except the one that operates on a DOM instance
+ come in overloaded triples. The first function in such a triple
+ reports error conditions exclusively by throwing exceptions. It
+ accumulates all the parsing and validation errors of the XML-DOM
+ stage and throws them in a single instance of the
+ <code>xml_schema::parsing</code> exception (described below).
+ The second and the third functions in the triple use callback
+ interfaces to report parsing and validation errors and warnings.
+ The two callback interfaces are <code>xml_schema::error_handler</code>
+ and <code>xercesc::DOMErrorHandler</code>. For more information
+ on the <code>xercesc::DOMErrorHandler</code> interface refer to
+ the Xerces-C++ documentation. The <code>xml_schema::error_handler</code>
+ interface is presented below:
+ </p>
+
+ <pre class="c++">
+class error_handler
+{
+public:
+ struct severity
+ {
+ enum value
+ {
+ warning,
+ error,
+ fatal
+ };
+ };
+
+ virtual bool
+ handle (const std::basic_string&lt;C>&amp; id,
+ unsigned long line,
+ unsigned long column,
+ severity,
+ const std::basic_string&lt;C>&amp; message) = 0;
+
+ virtual
+ ~error_handler ();
+};
+ </pre>
+
+ <p>The <code>id</code> argument of the <code>error_handler::handle</code>
+ function identifies the resource being parsed (e.g., a file name or
+ URI).
+ </p>
+
+ <p>By returning <code>true</code> from the <code>handle</code> function
+ you instruct the parser to recover and continue parsing. Returning
+ <code>false</code> results in termination of the parsing process.
+ An error with the <code>fatal</code> severity level results in
+ termination of the parsing process no matter what is returned from
+ the <code>handle</code> function. It is safe to throw an exception
+ from the <code>handle</code> function.
+ </p>
+
+ <p>The DOM-Tree stage reports error conditions exclusively by throwing
+ exceptions. Individual exceptions thrown by the parsing functions
+ are described in the following sub-sections.

+
+ <h2><a name="3.5">3.5 Reading from <code>std::istream</code></a></h2>
+
+ <p>When using an <code>std::istream</code> instance, you may also
+ pass an optional resource id. This id is used to identify the
+ resource (for example in error messages) as well as to resolve
+ relative paths. For instance:</p>
+
+ <pre class="c++">

+
+ <p>You can choose between writing XML to <code>std::ostream</code> or
+ <code>xercesc::XMLFormatTarget</code> and creating a DOM instance
+ in the form of <code>xercesc::DOMDocument</code>. Serialization
+ to <code>ostream</code> or <code>XMLFormatTarget</code> requires a
+ considerably less work while serialization to DOM provides
+ for greater flexibility. Each of these serialization functions
+ is discussed in more detail in the following sections.
+ </p>
+
+
+ <h2><a name="4.1">4.1 Initializing the Xerces-C++ Runtime</a></h2>
+
+ <p>Some serialization functions expect you to initialize the Xerces-C++
+ runtime while others initialize and terminate it as part of their
+ work. The general rule is as follows: if a function has any arguments
+ or return a value that is an instance of a Xerces-C++ type, then
+ this function expects you to initialize the Xerces-C++ runtime.
+ Otherwise, the function initializes and terminates the runtime for
+ you. Note that it is legal to have nested calls to the Xerces-C++
+ initialize and terminate functions as long as the calls are balanced.
+ </p>
+
+ <p>You can instruct serialization functions that initialize and terminate
+ the runtime not to do so by passing the
+ <code>xml_schema::flags::dont_initialize</code> flag (see
+ <a href="#4.3">Section 4.3, "Flags"</a>).
+ </p>
+
+ <h2><a name="4.2">4.2 Namespace Infomap and Character Encoding</a></h2>
+
+ <p>When a document being serialized uses XML namespaces, custom
+ prefix-namespace associations can to be established. If custom
+ prefix-namespace mapping is not provided then generic prefixes
+ (<code>p1</code>, <code>p2</code>, etc) are automatically assigned
+ to namespaces as needed. Also, if
+ you would like the resulting instance document to contain the
+ <code>schemaLocation</code> or <code>noNamespaceSchemaLocation</code>
+ attributes, you will need to provide namespace-schema associations.
+ The <code>xml_schema::namespace_infomap</code> class is used
+ to capture this information:</p>
+
+ <pre class="c++">
+struct namespace_info
+{
+ namespace_info ();
+ namespace_info (const std::basic_string&lt;C>&amp; name,
+ const std::basic_string&lt;C>&amp; schema);
+
+ std::basic_string&lt;C> name;
+ std::basic_string&lt;C> schema;
+};
+
+// Map of namespace prefix to namespace_info.
+//
+struct namespace_infomap: public std::map&lt;std::basic_string&lt;C>,
+ namespace_info>
+{
+};
+ </pre>
+
+ <p>Consider the following associations as an example:</p>
+
+ <pre class="c++">
+xml_schema::namespace_infomap map;
+
+map["t"].name = "http://www.codesynthesis.com/test";
+map["t"].schema = "test.xsd";
+ </pre>
+
+ <p>This map, if passed to one of the serialization functions,
+ could result in the following XML fragment:</p>
+
+ <pre class="xml">
+&lt;?xml version="1.0" ?>
+&lt;t:name xmlns:t="http://www.codesynthesis.com/test"
+ xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+ xsi:schemaLocation="http://www.codesynthesis.com/test test.xsd">
+ </pre>
+
+ <p>As you can see, the serialization function automatically added namespace
+ mapping for the <code>xsi</code> prefix. You can change this by
+ providing your own prefix:</p>
+
+ <pre class="c++">
+xml_schema::namespace_infomap map;
+
+map["xsn"].name = "http://www.w3.org/2001/XMLSchema-instance";
+
+map["t"].name = "http://www.codesynthesis.com/test";
+map["t"].schema = "test.xsd";
+ </pre>
+
+ <p>This could result in the following XML fragment:</p>
+
+ <pre class="xml">
+&lt;?xml version="1.0" ?>
+&lt;t:name xmlns:t="http://www.codesynthesis.com/test"
+ xmlns:xsn="http://www.w3.org/2001/XMLSchema-instance"
+ xsn:schemaLocation="http://www.codesynthesis.com/test test.xsd">
+ </pre>
+
+ <p>To specify the location of a schema without a namespace you can use
+ an empty prefix as in the example below: </p>
+
+ <pre class="c++">
+xml_schema::namespace_infomap map;
+
+map[""].schema = "test.xsd";
+ </pre>
+
+ <p>This would result in the following XML fragment:</p>
+
+ <pre class="xml">
+&lt;?xml version="1.0" ?>
+&lt;name xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+ xsi:noNamespaceSchemaLocation="test.xsd">
+ </pre>
+
+ <p>To make a particular namespace default you can use an empty
+ prefix, for example:</p>
+
+ <pre class="c++">
+xml_schema::namespace_infomap map;
+
+map[""].name = "http://www.codesynthesis.com/test";
+map[""].schema = "test.xsd";
+ </pre>
+
+ <p>This could result in the following XML fragment:</p>
+
+ <pre class="xml">
+&lt;?xml version="1.0" ?>
+&lt;name xmlns="http://www.codesynthesis.com/test"
+ xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+ xsi:schemaLocation="http://www.codesynthesis.com/test test.xsd">
+ </pre>
+
+
+ <p>Another bit of information that you can pass to the serialization
+ functions is the character encoding method that you would like to use.
+ Common values for this argument are <code>"US-ASCII"</code>,
+ <code>"ISO8859-1"</code>, <code>"UTF-8"</code>,
+ <code>"UTF-16BE"</code>, <code>"UTF-16LE"</code>,
+ <code>"UCS-4BE"</code>, and <code>"UCS-4LE"</code>. The default
+ encoding is <code>"UTF-8"</code>. For more information on
+ encoding methods see the
+ "<a href="http://en.wikipedia.org/wiki/Character_code">Character
+ Encoding</a>" article from Wikipedia.
+ </p>
+
+ <h2><a name="4.3">4.3 Flags</a></h2>
+
+ <p>Serialization flags are the last argument of every serialization
+ function. They allow you to fine-tune the process of serialization.
+ The flags argument is optional.
+ </p>
+
+
+ <p>The following flags are recognized by the serialization
+ functions:</p>
+
+ <dl>
+ <dt><code>xml_schema::flags::dont_initialize</code></dt>
+ <dd>Do not initialize the Xerces-C++ runtime.</dd>
+
+ <dt><code>xml_schema::flags::dont_pretty_print</code></dt>
+ <dd>Do not add extra spaces or new lines that make the resulting XML
+ slightly bigger but easier to read.</dd>
+
+ <dt><code>xml_schema::flags::no_xml_declaration</code></dt>
+ <dd>Do not write XML declaration (&lt;?xml ... ?>).</dd>
+ </dl>
+
+ <p>You can pass several flags by combining them using the bit-wise OR
+ operator. For example:</p>
+
+ <pre class="c++">
+std::auto_ptr&lt;type> r = ...
+std::ofstream ofs ("test.xml");
+xml_schema::namespace_infomap map;
+name (ofs,
+ *r,
+ map,
+ "UTF-8",
+ xml_schema::flags::no_xml_declaration |
+ xml_schema::flags::dont_pretty_print);
+ </pre>
+
+ <p>For more information on the Xerces-C++ runtime initialization
+ refer to <a href="#4.1">Section 4.1, "Initializing the Xerces-C++
+ Runtime"</a>.
+ </p>
+
+ <h2><a name="4.4">4.4 Error Handling</a></h2>
+
+ <p>As with the parsing functions (see <a href="#3.3">Section 3.3,
+ "Error Handling"</a>), to better understand error handling and
+ reporting strategies employed by the serialization functions, it
+ is useful to know that the transformation of a statically-typed
+ tree to an XML instance document happens in two stages. The first
+ stage, performed by the generated code, consist of building a DOM
+ instance from the statically-typed tree . For short, we will call
+ this stage the Tree-DOM stage. The second stage, performed by
+ Xerces-C++, consists of serializing the DOM instance into the XML
+ document. We will call this stage the DOM-XML stage.
+ </p>
+
+ <p>All serialization functions except the two that serialize into
+ a DOM instance come in overloaded triples. The first function
+ in such a triple reports error conditions exclusively by throwing
+ exceptions. It accumulates all the serialization errors of the
+ DOM-XML stage and throws them in a single instance of the
+ <code>xml_schema::serialization</code> exception (described below).
+ The second and the third functions in the triple use callback
+ interfaces to report serialization errors and warnings. The two
+ callback interfaces are <code>xml_schema::error_handler</code> and
+ <code>xercesc::DOMErrorHandler</code>. The
+ <code>xml_schema::error_handler</code> interface is described in
+ <a href="#3.3">Section 3.3, "Error Handling"</a>. For more information
+ on the <code>xercesc::DOMErrorHandler</code> interface refer to the
+ Xerces-C++ documentation.
+ </p>
+
+ <p>The Tree-DOM stage reports error conditions exclusively by throwing
+ exceptions. Individual exceptions thrown by the serialization functions
+ are described in the following sub-sections.
+ </p>
+
+ <h3><a name="4.4.1">4.4.1 <code>xml_schema::serialization</code></a></h3>
+
+ <pre class="c++">
+struct serialization: virtual exception
+{
+ serialization ();
+ serialization (const diagnostics&amp;);
+
+ const diagnostics&amp;
+ diagnostics () const;
+
+ virtual const char*
+ what () const throw ();
+};
+ </pre>
+
+ <p>The <code>xml_schema::diagnostics</code> class is described in
+ <a href="#3.3.1">Section 3.3.1, "<code>xml_schema::parsing</code>"</a>.
+ The <code>xml_schema::serialization</code> exception is thrown if
+ there were serialization errors reported during the DOM-XML stage.
+ If no callback interface was provided to the serialization function,
+ the exception contains a list of errors and warnings accessible using
+ the <code>diagnostics</code> function.
+ </p>
+
+
+ <h3><a name="4.4.2">4.4.2 <code>xml_schema::unexpected_element</code></a></h3>
+
+ <p>The <code>xml_schema::unexpected_element</code> exception is
+ described in <a href="#3.3.3">Section 3.3.3,
+ "<code>xml_schema::unexpected_element</code>"</a>. It is thrown
+ by the serialization functions during the Tree-DOM stage if the
+ root element name of the provided DOM instance does not match with
+ the name of the element this serialization function is for.
+ </p>
+
+ <h3><a name="4.4.3">4.4.3 <code>xml_schema::no_type_info</code></a></h3>
+
+ <p>The <code>xml_schema::no_type_info</code> exception is
+ described in <a href="#3.3.7">Section 3.3.7,
+ "<code>xml_schema::no_type_info</code>"</a>. It is thrown
+ by the serialization functions during the Tree-DOM stage when there
+ is no type information associated with a dynamic type of an
+ element. Usually, catching this exception means that you haven't
+ linked the code generated from the schema defining the type in
+ question with your application or this schema has been compiled
+ without the <code>--generate-polymorphic</code> option.
+ </p>
+
+ <h2><a name="4.5">4.5 Serializing to <code>std::ostream</code></a></h2>
+
+ <p>In order to serialize to <code>std::ostream</code> you will need
+ an object model, an output stream and, optionally, a namespace
+ infomap. For instance:</p>
+
+ <pre class="c++">
+// Obtain the object model.
+//
+std::auto_ptr&lt;type> r = ...
+
+// Prepare namespace mapping and schema location information.
+//
+xml_schema::namespace_infomap map;
+
+map["t"].name = "http://www.codesynthesis.com/test";
+map["t"].schema = "test.xsd";
+
+// Write it out.
+//
+name (std::cout, *r, map);
+ </pre>
+
+ <p>Note that the output stream is treated as a binary stream. This
+ becomes important when you use a character encoding that is wider
+ than 8-bit <code>char</code>, for instance UTF-16 or UCS-4. For
+ example, things will most likely break if you try to serialize
+ to <code>std::ostringstream</code> with UTF-16 or UCS-4 as an
+ encoding. This is due to the special value,
+ <code>'\0'</code>, that will most likely occur as part of such
+ serialization and it won't have the special meaning assumed by
+ <code>std::ostringstream</code>.
+ </p>
+
+
+ <h2><a name="4.6">4.6 Serializing to <code>xercesc::XMLFormatTarget</code></a></h2>
+
+ <p>Serializing to an <code>xercesc::XMLFormatTarget</code> instance
+ is similar the <code>std::ostream</code> case. For instance:
+ </p>
+
+ <pre class="c++">
+using std::auto_ptr;
+
+// Obtain the object model.
+//
+auto_ptr&lt;type> r = ...
+
+// Prepare namespace mapping and schema location information.
+//
+xml_schema::namespace_infomap map;
+
+map["t"].name = "http://www.codesynthesis.com/test";
+map["t"].schema = "test.xsd";
+
+using namespace xercesc;
+
+XMLPlatformUtils::Initialize ();
+
+{
+ // Choose a target.
+ //
+ auto_ptr&lt;XMLFormatTarget> ft;
+
+ if (argc != 2)
+ {
+ ft = auto_ptr&lt;XMLFormatTarget> (new StdOutFormatTarget ());
+ }
+ else
+ {
+ ft = auto_ptr&lt;XMLFormatTarget> (
+ new LocalFileFormatTarget (argv[1]));
+ }
+
+ // Write it out.
+ //
+ name (*ft, *r, map);
+}
+
+XMLPlatformUtils::Terminate ();
+ </pre>
+
+ <p>Note that we had to initialize the Xerces-C++ runtime before we
+ could call this serialization function.</p>
+
+ <h2><a name="4.7">4.7 Serializing to DOM</a></h2>
+
+ <p>The mapping provides two overloaded functions that implement
+ serialization to a DOM instance. The first creates a DOM instance
+ for you and the second serializes to an existing DOM instance.
+ While serializing to a new DOM instance is similar to serializing
+ to <code>std::ostream</code> or <code>xercesc::XMLFormatTarget</code>,
+ serializing to an existing DOM instance requires quite a bit of work
+ from your side. You will need to set all the custom namespace mapping
+ attributes as well as the <code>schemaLocation</code> and/or
+ <code>noNamespaceSchemaLocation</code> attributes. The following
+ listing should give you an idea about what needs to be done:
+ </p>
+
+ <pre class="c++">
+// Obtain the object model.
+//
+std::auto_ptr&lt;type> r = ...
+
+using namespace xercesc;
+
+XMLPlatformUtils::Initialize ();
+
+{
+ // Create a DOM instance. Set custom namespace mapping and schema
+ // location attributes.
+ //
+ DOMDocument&amp; doc = ...
+
+ // Serialize to DOM.
+ //
+ name (doc, *r);
+
+ // Serialize the DOM document to XML.
+ //
+ ...
+}
+
+XMLPlatformUtils::Terminate ();
+ </pre>
+
+ <p>For more information on how to create and serialize a DOM instance
+ refer to the Xerces-C++ documentation. In addition, the
+ <a href="http://wiki.codesynthesis.com/Tree/FAQ">C++/Tree Mapping
+ FAQ</a> shows how to implement these operations using the XSD
+ runtime utilities.
+ </p>
+
+ <h1><a name="5">5 Additional Functionality</a></h1>
+
+ <p>The C++/Tree mapping provides a number of optional features
+ that can be useful in certain situations. They are described
+ in the following sections.</p>
+
+ <h2><a name="5.1">5.1 DOM Association</a></h2>
+
+ <p>Normally, after parsing is complete, the DOM document which
+ was used to extract the data is discarded. However, the parsing
+ functions can be instructed to preserve the DOM document
+ and create an association between the DOM nodes and object model
+ nodes. When there is an association between the DOM and
+ object model nodes, you can obtain the corresponding DOM element
+ or attribute node from an object model node as well as perform
+ the reverse transition: obtain the corresponding object model
+ from a DOM element or attribute node.</p>
+
+ <p>Maintaining DOM association is normally useful when the application
+ needs access to XML constructs that are not preserved in the
+ object model, for example, text in the mixed content model.
+ Another useful aspect of DOM association is the ability of the
+ application to navigate the document tree using the generic DOM
+ interface (for example, with the help of an XPath processor)
+ and then move back to the statically-typed object model. Note
+ also that while you can change the underlying DOM document,
+ these changes are not reflected in the object model and will
+ be ignored during serialization. If you need to not only access
+ but also modify some aspects of XML that are not preserved in
+ the object model, then type customization with custom parsing
+ constructs and serialization operators should be used instead.</p>
+
+ <p>To request DOM association you will need to pass the
+ <code>xml_schema::flags::keep_dom</code> flag to one of the
+ parsing functions (see <a href="#3.2">Section 3.2,
+ "Flags and Properties"</a> for more information). In this case the
+ DOM document is retained and will be released when the object model
+ is deleted. Note that since DOM nodes "out-live" the parsing function
+ call, you need to initialize the Xerces-C++ runtime before calling
+ one of the parsing functions with the <code>keep_dom</code> flag and
+ terminate it after the object model is destroyed (see
+ <a href="#3.1">Section 3.1, "Initializing the Xerces-C++ Runtime"</a>).
+ The DOM association is also maintained in complete copies of the
+ object model (that is, the DOM document is cloned and associations
+ are reestablished).</p>
+
+ <p>To obtain the corresponding DOM node from an object model node
+ you will need to call the <code>_node</code> accessor function
+ which returns a pointer to <code>DOMNode</code>. You can then query
+ this DOM node's type and cast it to either <code>DOMAttr*</code>
+ or <code>DOMElement*</code>. To obtain the corresponding object
+ model node from a DOM node, the DOM user data API is used. The
+ <code>xml_schema::dom::tree_node_key</code> variable contains
+ the key for object model nodes. The following schema and code
+ fragment show how to navigate from DOM to object model nodes
+ and in the opposite direction:</p>
+
+ <pre class="xml">
+&lt;complexType name="object">
+ &lt;sequence>
+ &lt;element name="a" type="string"/>
+ &lt;/sequence>
+&lt;/complexType>
+
+&lt;element name="root" type="object"/>
+ </pre>
+
+ <pre class="c++">
+using namespace xercesc;
+
+XMLPlatformUtils::Initialize ();
+
+{
+ // Parse XML to object model.
+ //
+ std::auto_ptr&lt;type> r = root (
+ "root.xml",
+ xml_schema::flags::keep_dom |
+ xml_schema::flags::dont_initialize);
+
+ DOMNode* n = root->_node ();
+ assert (n->getNodeType () != DOMNode::ELEMENT_NODE);
+ DOMElement* re = static_cast&lt;DOMElement*> (n);
+
+ // Get the 'a' element. Note that it is not necessarily the
+ // first child node of 'root' since there could be whitespace
+ // nodes before it.
+ //
+ DOMElement* ae;
+
+ for (n = re->getFirstChild (); n != 0; n = n->getNextSibling ())
+ {
+ if (n->getNodeType () == DOMNode::ELEMENT_NODE)
+ {
+ ae = static_cast&lt;DOMElement*> (n);
+ break;
+ }
+ }
+
+ // Get from the 'a' DOM element to xml_schema::string object model
+ // node.
+ //
+ xml_schema::type&amp; t (
+ *reinterpret_cast&lt;xml_schema::type*> (
+ ae->getUserData (xml_schema::dom::tree_node_key)));
+
+ xml_schema::string&amp; a (dynamic_cast&lt;xml_schema::string&amp;> (t));
+}
+
+XMLPlatformUtils::Terminate ();
+ </pre>
+
+ <p>The 'mixed' example which can be found in the XSD distribution
+ shows how to handle the mixed content using DOM association.</p>
+
+ <h2><a name="5.2">5.2 Binary Serialization</a></h2>
+
+ <p>Besides reading from and writing to XML, the C++/Tree mapping
+ also allows you to save the object model to and load it from a
+ number of predefined as well as custom data representation
+ formats. The predefined binary formats are CDR (Common Data
+ Representation) and XDR (eXternal Data Representation). A
+ custom format can easily be supported by providing
+ insertion and extraction operators for basic types.</p>
+
+ <p>Binary serialization saves only the data without any meta
+ information or markup. As a result, saving to and loading
+ from a binary representation can be an order of magnitude
+ faster than parsing and serializing the same data in XML.
+ Furthermore, the resulting representation is normally several
+ times smaller than the equivalent XML representation. These
+ properties make binary serialization ideal for internal data
+ exchange and storage. A typical application that uses this
+ facility stores the data and communicates within the
+ system using a binary format and reads/writes the data
+ in XML when communicating with the outside world.</p>
+
+ <p>In order to request the generation of insertion operators and
+ extraction constructors for a specific predefined or custom
+ data representation stream, you will need to use the
+ <code>--generate-insertion</code> and <code>--generate-extraction</code>
+ compiler options. See the
+ <a href="http://www.codesynthesis.com/projects/xsd/documentation/xsd.xhtml">XSD
+ Compiler Command Line Manual</a> for more information.</p>
+
+ <p>Once the insertion operators and extraction constructors are
+ generated, you can use the <code>xml_schema::istream</code>
+ and <code>xml_schema::ostream</code> wrapper stream templates
+ to save the object model to and load it from a specific format.
+ The following code fragment shows how to do this using ACE
+ (Adaptive Communication Environment) CDR streams as an example:</p>
+
+ <pre class="xml">
+&lt;complexType name="object">
+ &lt;sequence>
+ &lt;element name="a" type="string"/>
+ &lt;element name="b" type="int"/>
+ &lt;/sequence>
+&lt;/complexType>
+
+&lt;element name="root" type="object"/>
+ </pre>
+
+ <pre class="c++">
+// Parse XML to object model.
+//
+std::auto_ptr&lt;type> r = root ("root.xml");
+
+// Save to a CDR stream.
+//
+ACE_OutputCDR ace_ocdr;
+xml_schema::ostream&lt;ACE_OutputCDR> ocdr (ace_ocdr);
+
+ocdr &lt;&lt; *r;
+
+// Load from a CDR stream.
+//
+ACE_InputCDR ace_icdr (buf, size);
+xml_schema::istream&lt;ACE_InputCDR> icdr (ace_icdr);
+
+std::auto_ptr&lt;object> copy (new object (icdr));
+
+// Serialize to XML.
+//
+root (std::cout, *copy);
+ </pre>
+
+ <p>The XSD distribution contains a number of examples that
+ show how to save the object model to and load it from
+ CDR, XDR, and a custom format.</p>
