Hi Kev --
Thanks for your reply. Could you post sample code for your two-pass
idea? I'm really new at XSL and I don't think I follow your idea.
Thanks,
Peter

Hi Peter,
This looks to me like a pretty standard solution to this
problem although its clearly inefficient for larger data
sets.
As an alternative I would be tempted to try a two pass
approach, the first to collect the position() of all your
headers in a variable and the second to chop and process a
nodeset of all the rows using a recursive template and the
position() data. This would exchange searching for nodeset
manipulation so your milage will vary on different
processors.
Kev.
