The example achieves this by customizing the type with +the mixed content model to include a DOM document that stores the data +as a raw XML representation. The customized type also provides its own +parsing constructor and serialization operator where the mixed content +is extracted from and inserted back to DOM, respectively. The use of +DOM for mixed content storage is one of the options. You may find other +data structures (e.g., a string) more suitable depending on your situation. + +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: + +people.xsd + XML Schema definition for a simple person record vocabulary. Each + record includes the bio element which represents arbitrary XHTML + fragments as mixed content. + +people.xml + Sample XML instance document. + +people.hxx +people.ixx +people.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 people.xsd + with the --custom-type option in order to customize the bio type. + +people-custom.hxx + Header file which defines our own bio class by inheriting from the + generated bio_base. It is included at the end of people.hxx using + the --hxx-epilogue option. + +people-custom.cxx + Source file which contains the implementation of our bio 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 bio information converted to text. + Finally, the driver serializes the object model back to XML. + +To run the example on the sample XML instance document simply execute: + +$ ./driver people.xml -- cgit v1.1
