Hi all,

I'm trying to parse some HTML forms to get the values from "name" and
"value" attributes and then to add them in a list. I'm encountering a
problem with the regular expressions and I can't figure out why the
expression is invalid.

Bellow is the code that I'm using:
    for lines in buffer.readlines():
      print lines
      regexp =3D 'value=3D"(.*)?"\s*name\s*=3D\s*"(.*:\d+:\d+)?"'
      print regexp
      p =3D re.search(regexp,lines)

The error message is:
    p =3D re.search(regexp,lines)
  File "/usr/lib/python2.2/sre.py", line 137, in search
    return _compile(pattern, flags).search(string)
  File "/usr/lib/python2.2/sre.py", line 229, in _compile
    raise error, v # invalid expression
error: nothing to repeat

Can anybody tell me what is wrong with the regular expression?? Also,
are any other possibilities to parse the HTML using functions already
implemented  (i.e. HTMLPasrse module) ??


Thanks,
Ovidiu
