Screenscraping, in python, a web page that requires javascript?


Is there a method, with python, of screenscraping a web page, if that web
page uses javascript?

I know about BeautifulSoup, but AFAIK at this time, BeautifulSoup is for
HTML that doesn't have embedded javascript.

Thanks!

Not pure CPython, no.

It's not that BeautifulSoup is unhappy with JS, it's just that there's
no support for executing the JS.

There are some Java libraries that know how to execute JS embedded in
web pages, which could be used from Jython:

http://htmlunit.sourceforge.net/

You can also automate a browser, but that still seems to be painful in
one way or another.

This view of strings is about a decade out of date with modern programmimg practice. From...

I am having a lot of problems trying to get a Python CGI to run. I have included 3 parts... 1) A simple stripped down python module. 2) An output of what I get when I do: python index.py (which not suprisingly should generate HTML output, and it does) 3) And the "error_log" output from the "server error" I get when I run it by typing in: http://localhost/cgi-bin/index.py

Hi! I'm having some problems correctly screenscraping and outputting e.g. Chinese characters from a Google translator search result. The output is always a garbled mess, not Chinese characters. German for instance works fine. Thanks for any hints...!! Some relevant parts from the PHP5: /******************/ header ('Content-type: text/html; charset=utf-8');

Hi all, I've been writing Javascript for quite a while now and have, of late, been writing quite a lot of AJAX and AJAX-related code. In the main, my dynamically generated pages are created using Perl on the backend, with Javascript providing limited frontend functionality. As an example, an expanding tree would be fully populated on the server-side and then presented to the browser, with Javascript and CSS being used to vary the...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
