使用美丽汤按类名获取内容 [英] Get contents by class names using Beautiful Soup

问题描述

使用Beautiful Soup模块，如何获取类名称为feeditemcontent cxfeeditemcontent的div标记的数据?是吗?

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']

或:

soup.find_all('class')

这是HTML来源:

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

这是Python代码:

and this is the Python code:

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

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

推荐答案

尝试一下，也许对于这个简单的东西来说太多了，但它可以起作用:

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
