Re: How to retrieve value(which is copied into RTF as

David,
     you are right. It has a performance impact which
I can see. As I hardly work on XSLT so never get any
chance to look into performance. 
To clarify, $leverreference contains "id" values and
profession contains id and name values. I need to
retrieve names from profession depending upon id
values in $leverreference RTF and display only unique
names with number of occurrence. I would appreciate
for any suggestion on performance.

regards.
Ranjan
I have atleast used 3 RTF to get the result.
