Would anyone show me how to use htmllib?

Thank you for the example.
I went back and take a look htmllib again. Some part makes more sense
now. Here is what I wanted to do:

I noticed that are lots of patterns in html pages, I want to extract
infomation out of html pages(based on patterns). I have done this using
perl's regular expression before. Now I am wondering if I can speed up
development process and have a stardard approach for this problem using
python htmllib.

For reference, htmllib library documenation metioned:
######################################################################
#This module defines a class which can serve as a base for parsing text
#files formatted in the HyperText Mark-up Language (HTML).
######################################################################

All of the examples I have seen are extracting URL links from a html
page. I was wondering if I can do more with this modules.
