Examples of DOMXPath

org.jaxen.dom.DOMXPath
An XPath implementation for the W3C DOM 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 {@link #selectNodes}method, as in the following example:
```
 XPath path = new DOMXPath("a/b/c"); List results = path.selectNodes(domNode); 
```
