I wrote one of these for the Advanced JDOM chapter in Brett's "Java and XML
2nd. edition".  The xpath was always positional because the example had to fit
in the book, but you could have allowed some sort of xpath style selection
pretty easily.  Alex Chaffee thought he was going to add this to his xpath
expression evaluator but I don't know if he ever got around to it.
