You could use the re module to search for  specific tags and then download
from there. Ther is a program called spyder.py out there that could give you
some ideas on how to write this program. It is used in Plucker to download
specific items from a website and then convert them into a portable document
format that can be read on a pda using their plucker software. The program
is open source and written entirely in python I believe. So read some of
their scripts to give you an idea how to accomplish this.

Hope this helps.
