Beautifulsoup unable to extract data using attrs=class

Question

I am extracting data for a research project and I have sucessfully used findAll('div', attrs={'class':'someClassName'}) in many websites but this particular website,

WebSite Link

doesn't return any values when I used attrs option. But when I don't use the attrs option I get entire html dom.

Here is the simple code that I started with to test it out:

soup = bs(urlopen(url))
for div in soup.findAll('div', attrs={'class':'data'}):
    print div

Answer 1

My code is working fine, with requests

import requests
from BeautifulSoup import BeautifulSoup as bs
#grab HTML
r = requests.get(r'http://www.amazon.com/s/ref=sr_pg_1?rh=n:172282,k%3adigital%20camera&keywords=digital%20camera&ie=UTF8&qid=1343600585')
html = r.text
#parse the HTML
soup = bs(html)

results= soup.findAll('div', attrs={'class': 'data'})

print results

Answer 2

If you or anyone reading this question would like to know the reason that the code wasn't able to find the attrs value using the code you've given (copied below):

soup = bs(urlopen(url))
for div in soup.findAll('div', attrs={'class':'data'}):
    print div

The issue is when you attempted to create a BeautifulSoup object soup = bs(urlopen(url)) as the value of urlopen(url) is a response object and not the DOM.

I'm sure any issues you had encountered could have been more easily resolved by using bs(urlopen(url).read()) instead.
