Get contents by class names using Beautiful Soup

Question

Using Beautiful Soup module, how can I get data of a div tag whose class name is feeditemcontent cxfeeditemcontent? Is it:

soup.class['feeditemcontent cxfeeditemcontent']

or:

soup.find_all('class')

This is the HTML source:

<div class="feeditemcontent cxfeeditemcontent">
    <div class="feeditembodyandfooter">
         <div class="feeditembody">
         <span>The actual data is some where here</span>
         </div>
     </div>
 </div> 

and this is the Python code:

 from BeautifulSoup import BeautifulSoup
 html_doc = open('home.jsp.html', 'r')

 soup = BeautifulSoup(html_doc)
 class="feeditemcontent cxfeeditemcontent"

Beautiful Soup 4 treats the value of the "class" attribute as a list rather than a string, meaning jadkik94's solution can be simplified:

from bs4 import BeautifulSoup                                                   

def match_class(target):                                                        
    def do_match(tag):                                                          
        classes = tag.get('class', [])                                          
        return all(c in classes for c in target)                                
    return do_match                                                             

soup = BeautifulSoup(html)                                                      
print soup.find_all(match_class(["feeditemcontent", "cxfeeditemcontent"]))

Try this, maybe it's too much for this simple thing but it works:

def match_class(target):
    target = target.split()
    def do_match(tag):
        try:
            classes = dict(tag.attrs)["class"]
        except KeyError:
            classes = ""
        classes = classes.split()
        return all(c in classes for c in target)
    return do_match

html = """<div class="feeditemcontent cxfeeditemcontent">
<div class="feeditembodyandfooter">
<div class="feeditembody">
<span>The actual data is some where here</span>
</div>
</div>
</div>"""

from BeautifulSoup import BeautifulSoup

soup = BeautifulSoup(html)

matches = soup.findAll(match_class("feeditemcontent cxfeeditemcontent"))
for m in matches:
    print m
    print "-"*10

matches = soup.findAll(match_class("feeditembody"))
for m in matches:
    print m
    print "-"*10

Answer 3

soup.findAll("div", class_="feeditemcontent cxfeeditemcontent")

So, If I want to get all div tags of class header <div class="header"> from stackoverflow.com, an example with BeautifulSoup would be something like:

from bs4 import BeautifulSoup as bs
import requests 

url = "http://stackoverflow.com/"
html = requests.get(url).text
soup = bs(html)

tags = soup.findAll("div", class_="header")

It is already in bs4 documentation.
