Now your talking!!!

Some kind of XPathDispatcher would be really cool.
A brute force approach is easy, an efficient non-brute force will require
some help from the XPath engine and is much more work :-(.
e.g. the brute force mechansim would be something like...
public XPathDispatcher implements ElementHandler {
private XPath xpath;
private ElementHandler child;
public XPathDispatcher( XPath xpath, ElementHandler child ) {
this.xpath = xpath;
this.child = child;
}
public XPathDispatcher( String xpath, ElementHandler child ) {
this.xpath = DocumentHelper.createXPath( xpath );
this.child = child;
}
public void onStart( ElementPath path ) {
// XXX don't know what to do here?
}
public void onEnd( ElementPath path )
Element element = path.getCurrent();
if ( xpath.matches( element ) ) {
child.onEnd( path );
}
}
}
