Getting all visible text from a webpage using Selenium

Using lxml, you might try something like this:

import contextlib
import selenium.webdriver as webdriver
import lxml.html as LH
import lxml.html.clean as clean

url="http://www.yahoo.com"
ignore_tags=('script','noscript','style')
with contextlib.closing(webdriver.Firefox()) as browser:
    browser.get(url) # Load page
    content=browser.page_source
    cleaner=clean.Cleaner()
    content=cleaner.clean_html(content)    
    with open('/tmp/source.html','w') as f:
       f.write(content.encode('utf-8'))
    doc=LH.fromstring(content)
    with open('/tmp/result.txt','w') as f:
        for elt in doc.iterdescendants():
            if elt.tag in ignore_tags: continue
            text=elt.text or ''
            tail=elt.tail or ''
            words=" ".join((text,tail)).strip()
            if words:
                words=words.encode('utf-8')
                f.write(words+'\n') 

This seems to get almost all of the text on www.yahoo.com, except for text in images and some text that changes with time (done with javascript and refresh perhaps).
