BeautifulSoup is the standard response.
I think lxml will not work very well unless the
html is extremely nicely formatted, but I could
For what you describe I would suggest developing
seat-of-the-pants heuristics -- just get the page
using httplib and then use string.find liberally.
I've had at least three consulting gigs solving
this problems using various techniques and the general
problem is quite difficult, but if you are trying to
parse just a few pages in simple ways developing
special purpose heuristics is pretty easy (until they
redesign the pages, which they will do every so often).

btw: If you have lots of money to spend on this
my former client connotate.com does this sort
of scraping (and I developed some of the code).

Hi Python web-sig users,
Thanks in advance and I am new to web-sig.
I am using Python 2.6 on Windows XP.
May I request you to assist me for the following please.
I like to extract web data from the site (http://finance.yahoo.com, for example).
The data may include Historical Prices, Key Statistics, News & Info, Headlines, etc. for a list of codes (such WOW, .... these are codes for company Ids).
I am trying to automate the extraction of data.
Is there any Python module or any assistance please?
Once again, thank you very much for the time you have given.
You might want to look into using eitherthe lxml or BeautifulSoup modules.
