Cannot select login form

Hi

I'm trying to download lesson notes and tips from duolingo.com. It requires login to access any lesson page, but I am unable to select the form

Code:

	def get_browser(self):
		br = BasicNewsRecipe.get_browser(self)
		br.open('http://en.duolingo.com/Signin')
		br.select_form(nr=0)

I get: mechanize._mechanize.FormNotFoundError: no form matching nr 0

On the page, you have to click Login button to access pop down login form. That's probably the problem. Any hint how I can deal with this?

Thanks in advance

If it is using javascript to login, then you have to watch the login requests using a browser extension like httptrack and duplicate those in python directly, using mechanize.Request, see for example the builtin recipe for wall street journal.

I just realized that every page on that site is just an empty div and approximately 2.5 tons of JavaScript! It's just too much for me to deal with

Edit: maybe it's not that bad. I think I can, I think I can, I think I can...

thank you, Kovid
