It's okay now.  I had to provide  one also for libxslt to get it working
though.  Is  it normal behaviour?  I  have to register the  callback for
both libraries  to handle  error messages (even  for errors  coming from
libxml2 only).

I mean saving the result of the XSL transformation to a string, but IIRC
it  is on  your TODO  list.  BTW,  saveResultToFilename didn't  work for
me.  No file was actually created.  As a workaround, I use the following
code:

    testfile = tempfile.TemporaryFile()
    style.saveResultToFd(testfile.fileno(), result)
    testfile.seek(0)
    content = <read whole file in a string>

The example did  not import libxslt.  As soon as  you import the libxslt
module, this example fails.

Thanks a lot for your help, and keep up the good work!
