webbrowser controls, manipulating javascript through Python

Hi!

The program that I'm doing is in Python.

Manually, one would be pasting certain texts in a textarea of a website, click submit, the page then would be redirected to the result, then copy and paste the result to an xml document. We were asked to automate this process. The website that I am referring to is in javascript so I figured the python program can manipulate its source. I looked into the webbrowser module but all I can do was open the url of the said website (i.e. webbrowser.open(url)).

Help!
