BeautifulSoup4获取“li a”，li内没有文本

Question

我需要帮助从一个网站获得一些特定的锚。网站有这样的结构

<li> This has a link <a href="#">1st link</a> </li> <li> <a href="#">2nd link</a> </li> <li> This also has a link <a href="#">1st link</a> </li>

Answer 1

您可以分析soup.contents的元素以确定是否只存在soup对象：

from bs4 import BeautifulSoup as soup
d = soup(s, 'html.parser')
results = [i for i in d.find_all('li') if all(not isinstance(c, str) or c == '\n' for c in i.contents)]

输出：

[<li>
  <a href="#">2nd link</a>
</li>]
