Please, spend the time to learn XSLT properly.  Many of these problems
can be easily solved with a correct understanding of things like
position() and xsl:number.  Where those do not work, a recursive
solution is often best.  You may have learned from other languages
that recursion is bad: this is NOT true for XSL.  The language is
carefully designed so that the XSLT processor can convert what you
write as recursion into a loop.

Follow the links on the web site you see quoted on all messages on
this list, or look at Mike Kays book XSLT programmers reference.
There you will find many examples of how to do these things in a way
that is both efficient and easy to understand.

I wonder if there is a market for a transformation engine that lets
you write the spec in Fortran ;-)
