hi!

i got the escape character bit, but i still get an error
>>> str='/My Documents/um_ajay.xml'
>>> re.subn('/', '\\', str)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "c:\Python23\lib\sre.py", line 151, in subn
    return _compile(pattern, 0).subn(repl, string, count)
  File "c:\Python23\lib\sre.py", line 258, in _subx
    template = _compile_repl(template, pattern)
  File "c:\Python23\lib\sre.py", line 245, in _compile_repl
    raise error, v # invalid expression
sre_constants.error: bogus escape (end of line)

any ideas?

cheers
