RE: XML to XML

It sounds as if your problem is in finding a design pattern for this
problem.

The problem is a multi-level grouping problem, where the first-level
grouping key is subsstring(code, 1, 1) and the second-level grouping key
is substring(code, 2, 1). 

With this knowledge you can apply the standard Muenchian grouping
technique as described at http://www.jenitennison.com/xslt/grouping, and
in all good textbooks.
