The +example achieves this by customizing the type to include the data +members and accessors/modifiers that represent the attribute as well as +the parsing constructor and serialization operator where the attribute +value is extracted from and inserted back to DOM, respectively. For +more information on the C++/Tree mapping customization see the C++/Tree +Mapping Customization Guide[1]. + +[1] http://wiki.codesynthesis.com/Tree/Customization_guide + +The example consists of the following files: + +wildcard.xsd + XML Schema definition for simple data type and element. + +wildcard.xml + Sample XML instance document. + +wildcard.hxx +wildcard.ixx +wildcard.cxx + C++ types that represent the given vocabulary, a set of parsing + functions that convert XML instance documents to a tree-like in-memory + object model, and a set of serialization functions that convert the + object model back to XML. These are generated by XSD from wildcard.xsd + with the --custom-type option in order to customize the data type. + +wildcard-custom.hxx + Header file which defines our own data class by inheriting from the + generated data_base. It is included at the end of wildcard.hxx using + the --hxx-epilogue option. + +wildcard-custom.cxx + Source file which contains the implementation of our data class. + +driver.cxx + Driver for the example. It first calls one of the parsing functions + that constructs the object model from the input file. It then prints + the data to STDERR, including the extra attribute. Finally, the driver + serializes the object model back to XML. + +To run the example on the sample XML instance document simply execute: + +$ ./driver wildcard.xml diff --git a/xsd/examples/cxx/tree/custom/wildcard/driver.cxx b/xsd/examples/cxx/tree/custom/wildcard/driver.cxx new file mode 100644 index 0000000..d63fb11 --- /dev/null +++ b/xsd/examples/cxx/tree/custom/wildcard/driver.cxx @@ -0,0 +1,48 @@ +// file : examples/cxx/tree/custom/wildcard/driver.cxx +// author : Boris Kolpackov <boris@codesynthesis.com> +// copyright : not copyrighted - public domain + +#include <memory> // std::auto_ptr +#include <iostream> + +#include "wildcard.hxx" + +using std::cerr;
