hmm.. your test app worked great, but when i try to use your functions in my 
code, I get the following error:

Traceback (most recent call last):
  File "./scripts/conv.py", line 119, in ?
    writeln('<entry>%s</entry>' % (procol(col)) )
  File "./scripts/conv.py", line 42, in procol
    msg = re.sub(r"<(Graphics\s+file:\s+)([^>]*)>", f, message)
  File "/usr/lib/python2.3/sre.py", line 143, in sub
    return _compile(pattern, 0).sub(repl, string, count)
  File "/usr/lib/python2.3/sre.py", line 257, in _subx
    template = _compile_repl(template, pattern)
  File "/usr/lib/python2.3/sre.py", line 237, in _compile_repl
    p = _cache_repl.get(key)
TypeError: list objects are unhashable



However, I'm sure that the line:

writeln('<entry>%s</entry>' % (procol(col)) )

passes a string to the function... the functions themselves remain 
unchanged...

Given that I'm passing a string to the procol function (as you did in your 
code), surely everything should work?

still stumped :-/


Thanks,
