Newbie Problem

Hello List,

I have a problem, I am not able to access any nodes/values from a Loop.

I have a sorted result tree fragment in a variable, I am using msxsl 
node-set to loop through it.
Now when I need to access the other nodes of the document I am not able to 
do so.
Pl. see below for the partial xsl and xml code. I have put two comments in 
the xsl file one where I need the external node values but not able to 
retrieve and second where I am able to retreive but do not need
How can I access the outer/external nodes inside the loop, I also tried 
using key() but it also didn't work inside the loop. It was working fine 
outside the loop.
P.S. This xsl code is a part of a bigger xsl file.

Any advice will be very helpful. Thanks in advance.
