Examples of org.jaxen.javabean.JavaBeanXPath

org.jaxen.javabean.JavaBeanXPath
An XPath implementation for JavaBeans.
This is the main entry point for matching an XPath against a JavaBean tree. You create a compiled XPath object, then match it against one or more context nodes using the {@link #selectNodes(Object)}method, as in the following example:
```
 Node node = ...; XPath path = new JavaBeanXPath("a/b/c"); List results = path.selectNodes(node); 
```
