((?:[^<]|<(?!/p>))+)

It's not that different from the pattern =E3=80=8Calt=3D"[^"]+"=E3=80=8D ea= rlier in the regex. The capture group accepts one or more characters that either aren't '<', or that are '<' but are not immediately followed by '/p>'. Thus it stops capturing when it sees exactly '

' without consuming the '<'. Using my regex with the example that you posted earlier demonstrates that it works: >>> import re >>> s =3D '''

''' >>> print re.sub(pattern, replace, s)
