Given an xpath and an xml document, I would like to create the bit
vector which selects the characters from the xml document which
correspond to text which would be selected by that xpath.  Or I could
probably live with a boxed list of the selected items.

I started going down that path with xml/sax but I am hampered by
a lack of understanding of what I am working with, and I am beginning
to think I am using the wrong tool for the job.  (I can not find any
documentation on how to extract my position.  I can not find any
documentation on how to select the literal text of all of an element's
attributes either.)

Does anyone have a useful approach here?

Thanks,
