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.
