I’d like to do a very simple replacement using Beautiful Soup. Let’s say I want to visit all A tags in a page and append “?foo” to their href. Can someone post or link to an example of how to do something simple like that?

    from BeautifulSoup import BeautifulSoup

soup = BeautifulSoup('''
<html>
   <head><title>Testing</title></head>
   <body>
     <a href="http://foo.com/">foo</a>
     <a href="http://bar.com/bar">Bar</a>
   </body>
</html>''')

for link in soup.findAll('a'): # find all links
    link['href'] = link['href'] + '?foo'

print soup

    That prints:

    <html>
<head><title>Testing</title></head>
<body>
<a href="http://foo.com/?foo">foo</a>
<a href="http://bar.com/bar?foo">Bar</a>
</body>
</html>

    The documentation also has some examples for changing attributes. It is an extensive tutorial that covers all common aspects of BeautifulSoup. I don’t know what is missing from the documentation, maybe you should clarify.
