New Revision: 190347

URL: http://svn.apache.org/viewcvs?rev=190347&view=rev
Log:
Adding the XPath implementation based on Jaxen. This implementation still have some problems with the namespaces but works for the default case. This is not checked in to the main tree due to dependency on the Jaxen jars.
