xslt and python - which module??

[Markus Jais]

hello
I found on the web that there are some options for
python and xslt
for example a wrapper around Xalan.

can anybody give me a hint which xslt implementation would be best
I do not need speed, so it has not to be a C/C++ implementation
with a python wrapper.

in fact, a pure python implementation would have the advantage that
I can read the source.
(I can also read C source, but I hate reading C source!)

thanks in advance for any answers

regards
markus
