XOM API for Processing XML with Java

[Mike Miller <mm8041 AT gmail.com>]

Ok, I suppose some research is in order.  I'm getting lazy as I get older
and really wanted
something like:  well just do this or put that in your xpath query and it
will work ;-)

BTW:  I did see an XOM example somewhere, where a person showed you do
something
like:  doc.query("/*:tag1/*:tag2");   so as to wildcard or ignore namespace
issues (which is
what I wanted to do).  But XOM threw an exception about having a colon in
the xpath.
Is this doable?

Thanks,
Mike
