如何找到类元素 [英] How to find elements by class

问题描述

我在用Beautifulsoupclass属性的麻烦解析HTML元素。在code看起来像这样

I'm having trouble parsing html elements with "class" attribute using Beautifulsoup. The code looks like this

soup = BeautifulSoup(sdata)
mydivs = soup.findAll('div')
for div in mydivs: 
    if (div["class"]=="stylelistrow"):
        print div

我得到后，在同一行一个错误的脚本完成。

I get an error on the same line "after" the script finishes.

File "./beautifulcoding.py", line 130, in getlanguage
  if (div["class"]=="stylelistrow"):
File "/usr/local/lib/python2.6/dist-packages/BeautifulSoup.py", line 599, in __getitem__
   return self._getAttrMap()[key]
KeyError: 'class'

我如何摆脱或这个错误？

How do I get rid or this error?

推荐答案

您可以细化搜索，只找到一个给定的类这些div：

You can refine your search to only find those divs with a given class:

mydivs = soup.findAll("div", { "class" : "stylelistrow" })
