Hello,

I've been using XOM for a few months now, and I really like it. I find it useful, simple, and elegant. However, occasionally I come across something I can't find an obvious way to do. Here's one:

Given two nodes in the same document, Is there a good way to determine which of the nodes precedes the other in normal document order? Assuming they are non-identical, of course. The API, FAQ, and tutorial haven't given me any clues. I suspect you could do it with XPath, but there's that restriction about query() only returning a nodeset.

I can think of very cumbersome ways of doing it, but I'm looking for something that will be relatively efficient. Maybe I've missed something obvious. Any suggestions would be very welcome.

Thanks,
Gregory Garretson
