The crux if it is that the 'collection()' function is implementation dependent. I've been trying with saxon for a long while and could not find any documentation or examples. After many attempts at searching (Google), and some dumb luck (I searched the main saxon documentation toc for collection), I found saxon's documentation page: http://www.saxonica.com/documentation/sourcedocs/collections.html Still, no examples, but better. From that page, I think I can probably get my stuff going. What I wanted to do at the time was more of a small itch than and real need, so I tended to look into it somewhat shallowly and sporadialy. NOTE: I was stuck with a non Internet connected machine, so I had to search later, from other machines. I tried downloading the saxon documentation, but all seemed incomplete. I grabbed saxon9, and just recently grabbed it's doc distro, but have not tried to search it for this. Maybe I will. I would (personally) like to see the Saxon Documentation rendered into many forms (PDF, HTML, CHM) from something like DocBook. It would also be _very_ helpful if there were more examples. I've been meaning to ask if I could help do this (at least to convert the HTML documentation tree to DocBook), but never got around to it. If you're using an all-in-one editor, you'll have to dig into it to see what back end they use. I believe oXygen XML uses Saxon (but I'm not certain). Yes, oXygen does support Saxon. Using something like collection("somefiledirectory") that contains all XML files should be able to get something you wanted. Unless, you want other things along with it, which then you might have to show what you got so far. This is one of those things that seems sort of simple when I find the answer, but was completely baffling beforehand - particularly since I could not seem to find anything online. I have to agree that right now there are some thing that ought to be simple enough, but since XQuery is so new, there are not that many examples for every use case Hope this helps.
