That said, we need to get that info; the process of extracting information from web pages is knows as web scraping, and note that's is a very fragile process: every time the webpage changes, it's likely you'll have to modify the code that parses it.
Thanks to Ian blogpost, I discovered how nice is to use lxml to do web scraping, in particular in association with Firebug Firefox addon: it's just a simple process of:
- take the page;
- generate the lxml tree;
- with Firebug find the XPath to the element you need;
- loop / parse / have fun :)
