For more information on maintaining association -with the underlying DOM document, refer to Section 5.1, "DOM Association" -in the C++/Tree Mapping User Manual. - -You will need the XQilla library[1] which provides XQuery and XPath 2 -support on top of Xerces-C++ in order to build and run this example. - -[1] http://xqilla.sourceforge.net - -The example consists of the following files: - -people.xsd - XML Schema definition for a simple person record vocabulary. - -people.xml - Sample XML instance document. - -people.hxx -people.cxx - C++ types that represent the person record vocabulary and a set of - parsing functions that convert XML instance documents to a tree-like - in-memory object model. These are generated by XSD from people.xsd. - -dom-parse.hxx -dom-parse.cxx - Definition and implementation of the parse() function that parses an - XML document to a DOM document. - -driver.cxx - Driver for the example. It first calls the above parse() function to - parse the input file to a DOM document using XQilla-provided DOM - Implementation with support for XPath 2. It then parses the DOM - document to the object model.
