Yes. It's been at the back of my head that it would be a nice idea - when
I first started on contrib/xml and /xml2 array support was rather
primitive.

Well, if you like the way that contrib/xml2 works, I would add it there,
but I'm obviously biased. It could just be another wrapper around
pgxml_xpath but use its own traversal of the nodeset instead of
pgxmlnodesettotext. I can't speak for whether anyone else is doing
anything similar, but I haven't heard anyone say so!

Thanks for your interest
