This example is similar to the 'caching' +example except that it loads the binary representation of the schemas +embedded into the application instead of pre-parsing external schema files. + +The example consists of the following files: + +xsdbin.cxx + Tool for converting one or more XML Schema files to the compressed binary + representation. The output is written as a pair of C++ source files + containing the array with the binary data. Use the --help option to see + the tool's usage information. + +library.xsd + XML Schema which describes a library of books. + +library.xml + Sample XML instance document. + +library.hxx +library.cxx + C++ types that represent the given vocabulary and a set of parsing + functions that convert XML instance documents to a tree-like in-memory + object model. These are generated by the XSD compiler from library.xsd. + +library-schema.hxx +library-schema.cxx + Binary representation of the library.xsd schema. These files are generated + by the xsdbin tool. + +grammar-input-stream.hxx +grammar-input-stream.cxx + Input stream implementation with the special-purpose schema grammar + decompression algorithm. It is used to load the binary schema representation + produced by the xsdbin tool. + +driver.cxx + Driver for the example. It first sets up the Xerces-C++ DOM parser and + loads the embedded binary schema grammar for validation. It then performs + ten iterations that parse the input file to a DOM document using the DOM + parser and call one of the parsing functions that constructs the object + model from this DOM document. On each iteration the driver prints a number + of books in the object model to STDERR. + +To run the example on the sample XML instance document simply execute: + +$ ./driver library.xml |
