Examples of org.jaxen.XPath

org.jaxen.XPath
Defines the interface to an object which represents an XPath 1.0 expression which can be evaluated against a variety of different XML object models.
Most of the evaluation methods take a context object. This is typically a node or node set object (which is typically a List of node objects) or a Jaxen Context object. A null context is allowed, meaning that there is no XML nodes on which to evaluate.
