Don't have a link to a howto. But you're halfway there. urllib (and
urllib2) will get HTML text from the websites. Pulling data from it
sort of depends on the nature of the HTML. If it's well-structured
XHTML, you can use your favorite xml library. if it's well structured
HTML, you can try htmllib, but it's pretty primitive. If it's not
well-structured, you can use BeautifulSoup. I've used it to pull data
from tables. The problem with any of this is that your code really
depends on the structure - or lack thereof - of the HTML you're
scraping. If they change it, your code breaks.
