twill with XHTML (not viewing HTML)
Since I couldn't find this anywhere, I'll add it here for those who have the same problem: I was trying to test a website with twill and got this at the end of my traceback: raise BrowserStateError("not viewing HTML") BrowserStateError: not viewing HTML After spending a bunch of time making sure that, yes, it was spitting out HTML, I figured out that it specifically means that twill (actually mechanize) doesnt like X HTML. You can likely fix it by adding this at the top of the script: b = twill.get_browser() b._browser._factory.is_html = True twill.browser = b Presumably, there's a real reason that check is in place, but works-4-me...
