Python Screen Scraper

[James Stroud]

Hello,

Does anyone know of an example, however modest, of a screenscraper 
authored in python? I am using Firefox.

Basically, I am answering problems via my browser and being scored for 
each problem. I have a tendency to go past my peak for training 
efficiency, so I would like to scrape the result page for each problem I 
answer, compile statistics, and have a program alert me when I should 
stop (based on score and accuracy--assuming training value is related to 
changes in these metrics).

I have no idea how to go about writing such a beast and I am hoping that 
I could get some pointers or an example that could get me going in the 
right direction.

Parsing, etc, is not a problem, but I'm not exactly sure how I might 
interface python with Firefox, forwarding scraped pages to my browser 
(or forwarding from the browser to the scraper).

Thanks in advance for any help or advice.

James
