Re: test if null
> so DC's node() won't work either. Please go to the home page for this list and read the posting guidelines and try to formulate your question in a way that you have a chance of understanding the answer. You have been given several correct answers to the question that you have asked but you keep asserting that something didn't work (you don't say what you did, or what happened) so either you asked the wrong question, or you are interpretting the answer incorrectly. I would guess that you are not taking account of the current context when you execute the code. You ask: how do I get from here to the road? you get the answer, open the door and walk down the path you reply there is no door. it turns out that you are already outside the house at the point you try to interpret the answer, so you just need to "walk down the path" or perhaps you are in a different room, so you need to walk in to the hall before opening the door. If you don't say, we can only guess... David ________________________________________________________________________ This e-mail has been scanned for all viruses by Star.
