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. Finally, it prepares and executes + an XPath query on the underlying DOM document and then handles + the result by getting back from the returned DOM nodes to object + model nodes. + +To run the example on the sample XML document simply execute: + +$ ./driver people.xml |
