Hi David and Michael

I feel rather silly but Ive tried out both your <xsl:for-each> statements and they dont seem to work for me. I dont really know what the cause is coz I've tried checking other dependencies and they're working fine.

My problem really is trying to interact between two XML documents. I need to determine whether the top-level element of XML doc 1 is present in XML doc 2 (which I've done). I then need to determine whether the defining sub-element of the top-level element in doc 1 is also present in XML doc 2 (this part is becoming a nightmare for me).

For e.g. I have a top-level element 'Pain' and a sub-element (instance of Pain) viz. 'Headache' in XML doc 1. I want to check whether 'Pain' exists in XML doc 2 and whether it has a child (or grandchild) named 'Headache' as well. If it does then I'll proceed to extract other bits which have been said about 'headache' in XML doc 2.

I'm seriously stuck with this problem and one of the main reasons is my background in procedural programming. I could probably have done this bit using Java in 5mins but its taking me forever to get it done in XSLT. But I want to use XSLT as its a very powerful language and will ultimately be the best choice for my requirements.

Would sincerely appreciate your help.
