Preferably you don't, use an HTML parser. It is both easier and
more reliable since it is almost impossible to handle all HTML
constructs reliably using regex.

BeautifiulSoup is a good HTML parser although you can use the ones
that are in the standard library too.

Of course it may not be an HTML file in which case regex may or
may not be appropriate, but there are several other parsing modules
around, a quick search of the recent list archives will reveal several
discussions.
