[jdom-interest] XPath from Element

[Jason Hunter]

There's no direct method.  It'd be easy to write by walking up the tree 
and counting your place along the way.  Of course, the only path you can 
get from a tool is fragile and based on things like index which aren't 
the kind of general XPath a person can write which more describes the 
element's characteristics than it's current locatoin.

Why do you need this?
