Why would you do this? That is, you are pulling data from a database
into Python, then transforming it into XML, then running that XML
through an XSLT transformation. Why not pull the data into Python,
manipulate them in Python, then output as the end-result XML? That
is, transcribe from Python directly to the desired final XML format?
I can think of a couple of reasons to do it your way -- the XSLT
engine might well be faster than the Python transformation, it might
be easier to output simple XML and then expand it via XSLT, etc. --
but I'm wondering if you've considered the above simpler path? It
might make your life easier.

I'm hardly an expert, and your email doesn't present enough data to
make any specific recommendations, but I'd suggest using (c)
ElementTree as your XML library, if it meets your requirements. You
could pull the data in, do your manipulations in Python, then create
your XML using ElementTree. And it will solve your installation
issues if you can afford to wait long enough -- it will be in the
standard library for Python 2.5. Otherwise, ElementTree itself is
pure Python, and is thus easily installed, though there is an
optional C extension (cElementTree) that will improve performance.
