I'm trying to develop a simple web scraper. I want to extract plain text without HTML markup. My code works on plain (static) HTML, but not when content is generated by JavaScript embedded in the page.

In particular, when I use urllib2.urlopen(request) to read the page content, it doesn't show anything that would be added by the JavaScript code, because that code isn't executed anywhere. Normally it would be run by the web browser, but that isn't a part of my program.

How can I access this dynamic content from within my Python code?
