How can I render JavaScript HTML to HTML in python

Question

I have looked around and only found solutions that render a URL to HTML. However I need a way to be able to render a webpage (That I already have, and that has JavaScript) to proper HTML.

Want: Webpage (with JavaScript) ---> HTML

Not: URL --> Webpage (with JavaScript) ---> HTML

I couldn't figure out how to make the other code work the way I wanted.

This is the code I was using that renders URLs: http://webscraping.com/blog/Scraping-JavaScript-webpages-with-webkit/

For clarity, the code above takes a URL of a webpage that has some parts of the page rendered by JavaScript, so if I scrape the page normally using say urllib2 then I won't get all the links etc that are rendered as after the JavaScript.

However I want to be able to scrape a page, say again with urllib2, and then render that page and get the outcome HTML. (Different to the above code since it takes a URL as it's argument.

Any help is appreciated, thanks guys :)

Answer 1

try webdriver.Firefox().get('url')

Answer 2

You can pip install selenium from a command line, and then run something like:

from selenium import webdriver
from urllib2 import urlopen

url = 'http://www.google.com'
file_name = 'C:/Users/Desktop/test.txt'

conn = urlopen(url)
data = conn.read()
conn.close()

file = open(file_name,'wt')
file.write(data)
file.close()

browser = webdriver.Firefox()
browser.get('file:///'+file_name)
html = browser.page_source
browser.quit()
