public class JDOMXPath
extends BaseXPath

An XPath implementation for the JDOM model

This is the main entry point for matching an XPath against a DOM tree. You create a compiled XPath object, then match it against one or more context nodes using the BaseXPath.selectNodes(Object) method, as in the following example:

 Object jdomNode = ...; // Document, Element etc.
 XPath path = new JDOMXPath("a/b/c");
 List results = path.selectNodes(jdomNode);
