org.jaxen.dom.DocumentNavigator

Interface for navigating around the W3C DOM Level 2 object model.

This class is not intended for direct usage, but is used by the Jaxen engine during evaluation.

This class implements the org.jaxen.DefaultNavigator interface for the Jaxen XPath library, version 1.0beta3 (it is not guaranteed to work with subsequent releases). This adapter allows the Jaxen library to be used to execute XPath queries against any object tree that implements the DOM level 2 interfaces.

Note: DOM level 2 does not include a node representing an XML Namespace declaration. This navigator will return Namespace decls as instantiations of the custom {@link NamespaceNode} class, andusers will have to check result sets to locate and isolate these.
