This directory contains a number of examples that show how to use the C++/Tree mapping. The following list gives an overview of each example. See the README files in example directories for more information on each example. hello A simple "Hello, world!" example that shows how to parse XML documents. library Shows hot to handle more complex data structures, use the ID/IDREF cross-referencing mechanism, use the xsd:enumeration to C++ enum mapping, modify the object model, and serialize the modified object model back to XML. polymorphism Shows how to use XML Schema polymorphism features such as the xsi:type attribute and substitution groups. xpath Shows how to use the C++/Tree mapping together with XPath. wildcard Shows how to use the optional wildcard mapping to parse, access, modify, and serialize the XML data matched by XML Schema wildcards (any and anyAttribute). mixed Shows how to access the underlying DOM nodes to handle raw, "type- less content" such as mixed content models, anyType/anySimpleType, and any/anyAttribute. multiroot Shows how to handle XML vocabularies with multiple root elements. See also the messaging example. messaging Shows how to handle XML vocabularies with multiple root elements using the element type and element map features of the C++/Tree mapping. caching Shows how to parse several XML documents while reusing the underlying XML parser and caching the schemas used for validation. performance Measures the performance of parsing and serialization. This example also shows how to structure your code to achieve the maximum performance for these two operations. custom/ A collection of examples that show how to customize the C++/Tree mapping by using custom C++ classes instead of or in addition to the generated ones. See the accompanying README file for an overview of each example in this directory. streaming Shows how to create an XML document by performing multiple serializations of its smaller parts. This can be useful when the document is too large to fit into memory or when the other end needs to start processing without waiting for the whole document (streaming). binary/ A collection of examples that show how to serialize the object model into a number of predefined and custom binary formats. dbxml Shows how to use the C++/Tree mapping on top of the Berkeley DB XML embedded XML database.
