Good to hear from you again, Harald! I didn't recognize your "From"
address, but when I looked into the details, I recognized your name from
when we talked about some very early incarnations of pyparsing.

Pyparsing ships with JPG and PNG files containing class diagrams, plus an
htmldoc directory containing epydoc-generated help files.
There are also about 20 example programs included (also accessible in the
wiki).

I briefly considered what this grammar might look like, and rejected it as
much too complicated compared to .split("<***>"). You could also look into
using scanString instead of transformString (scanString reports the location
within the string of the matched text). Then when matching on a ";", use
the match location to help slice up the string and append to a list. But
again, this is so much more complicated than just .split("<***>"), I
wouldn't bother other than as an exercise in learning scanString.
Good luck!
