Is possible to combine handle_data and regular expressions?

[ProvoWallis]

Hi,

I've experimented with regular expressions to solve my problems in the
past but I have seen so many comments about HTMLParser and sgmllib that
I thought I would try a different approach this time so I tried using
HTMLParser.

I want to search through my SGML file for various strings of text and
find out what section they're in. What I have here does this to a
certain extent but I was wondering if I could make handle_data and
regular expressions work together to make this work a little better.

For instance, when I search for "above" as I am here, I just get
something like this: '174.114[1]':'above' but this isn't very useful
b/c I want to know the context of above (i.e., the informaiton on
either side the above) and maybe even us a regular expression to filter
the search a little more.

Any ideas?

As always, I'd appreciate feedback on my efforts.

Thanks,

Greg
