RE: xpath question

[Brian Dupras <briand at centera dot com>]

What I need is the node to be included if and only if the pp:attr is present
*and* has a non-empty value.

Three cases:
<ns:elem/> (don't want a match)
<ns:elem ns:attr=''/> (don't want a match)
<ns:elem ns:arrt='something'/> (DO want a match)

It sounds like I'm on the right track.

Thanks

Brian
