This example shows how to use the C++/Tree mapping together with XPath. In particular, it shows how to execute an XPath query on the underlying DOM document and then handle the result using the more convenient object model representation. 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 Xerces-C++ 3.x.y/XQilla 2.2.x. 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. driver-2.cxx Driver for Xerces-C++ 2.x.y/XQilla 2.1.x. It performs the same set of actions as driver.cxx above. To run the example on the sample XML document simply execute: $ ./driver people.xml
