使用BeautifulSoup删除特定类的div

Question

我想div从soup对象中删除特定的.
我正在使用python 2.7和bs4.

根据我们可以使用的文档div.decompose().

但这会删除所有的div.如何删除div特定类？

Answer 1

当然,你可以select,find或find_all将div在通常的方式兴趣s,然后叫decompose()上这些div.

例如,如果要删除所有带有类的div sidebar,可以使用

# replace with `soup.findAll` if you are using BeautifulSoup3
for div in soup.find_all("div", {'class':'sidebar'}): 
    div.decompose()

如果你想删除一个特定的div id,比如说main-content,你可以用

soup.find('div', id="main-content").decompose()

Answer 2

这将有助于您:

from bs4 import BeautifulSoup

markup = '<a>This is not div <div class="1">This is div 1</div><div class="2">This is div 2</div></a>'
soup = BeautifulSoup(markup,"html.parser")
a_tag = soup

soup.find('div',class_='2').decompose()

print a_tag

输出:

<a>This is not div <div class="1">This is div 1</div></a>

如果有帮助,请告诉我

Answer 3

希望对您有所帮助：

from bs4 import BeautifulSoup
from bs4.element import Tag

markup = '<a>This is not div <div class="1">This is div 1</div><div class="2">This is div 2</div></a>'
soup = BeautifulSoup(markup,"html.parser")

for tag in soup.select('div.1'):
  tag.decompose()

print(soup)
