Python的BeautifulSoup的findAll由＆QUOT;类＆QUOT;属性 [英] Python BeautifulSoup findAll by "class" attribute

问题描述

我要做到以下几点code，这是BS文件说，做，唯一的问题是，单词类不只是一个字。它可以在HTML里面可以找到，但它也导致此code抛出异常蟒蛇关键字。

那么，如何做到以下几点？

  soup.findAll（UL中，class =得分）
 

解决方案

您的问题似乎是，你期望 find_all 在汤中找到您的字符串精确匹配。 事实上：

  

当您搜索匹配特定CSS类的标记，你
  对任何CSS类的匹配：

您可以正常搜索类标记作为@alKid说。您也可以搜索与类_ 关键字ARG。

  soup.find_all（UL，类_ =得分）
 

I want to do the following code, which is what BS documentation says to do, the only problem is that the word "class" isn't just a word. It can be found inside HTML, but it's also a python keyword which causes this code to throw an error.

So how do I do the following?

soup.findAll('ul', class="score")

解决方案

Your problem seems to be that you expect find_all in the soup to find an exact match for your string. In fact:

When you search for a tag that matches a certain CSS class, you’re matching against any of its CSS classes:

You can properly search for a class tag as @alKid said. You can also search with the class_ keyword arg.

soup.find_all('ul', class_="score")
