We have developed a web based application, with user login etc, and we developed a python application that have to get some data on this page.
Is there any way to communicate python and system default browser ?
Our main goal is to open a webpage, with system browser, and get the HTML source code from it ? We tried with python webbrowser, opened web page succesfully, but could not get source code, and tried with urllib2, in that case, i think we have to use system default browser's cookie etc, and i dont want to this, because of security.
Have a look at the nltk module---they have some utilities for looking at web pages and getting text. There's also BeautifulSoup, which is a bit more elaborate. I'm currently using  both to scrape web pages for a learning algorithm---they're pretty widely used modules, so that means you can find lots of hints here :)
