Is there any reason why we can't just use something like awk? It's
installed almost everywhere (it may be required, not sure) and a lot
more people know how to use it. I havn't managed to wrap my brain
around xslt yet.
The input file could be simply line based. Attached is a simple script
that takes the input below and produces something resembling what you
suggested. It wouldn't be too hard to get it to produce multiple output
formats and dump the output to different files...
