使用BeautifulSoup查找具有特定孩子的元素 [英] Find elements which have a specific child with BeautifulSoup

问题描述

使用BeautifulSoup，如何访问具有特定div作为孩子的<li>?

With BeautifulSoup, how to access to a <li> which has a specific div as child?

示例:如何访问以Email作为子div的li的文本(即[e-mail])?

Example: How to access to the text (i.e. [e-mail]) of the li which has Email as child div?

<li>
  <div>Country</div>
  Germany
</li>
<li>
  <div>Email</div>
  [e-mail]
</li>

我尝试手动执行此操作:在所有li上循环播放，对于每个li，在所有子div上重新循环播放，以检查文本是否为Email等，但是我确定存在一个带有BeautifulSoup的版本更加聪明.

I tried to do it manually: looping on all li, and for each of them, relooping on all child div to check if text is Email, etc. but I'm sure there exists a more clever version with BeautifulSoup.

推荐答案

有多种方法可以解决此问题.

There are multiple ways to approach the problem.

一种选择是通过文本找到Email div 并获取

One option is to locate the Email div by text and get the next sibling:

soup.find("div", text="Email").next_sibling.strip()  # prints "[e-mail]"
