问题描述
如何使用python 2.6删除一切，包括< div class =comment> ....删除所有....< / div>
我尝试了各种方式使用re.sub没有任何成功
谢谢
解决方案
解析器如 BeautifulSoup ：
>>>来自BeautifulSoup import BeautifulSoup
>>>> soup = BeautifulSoup（'< body>< div> 1< / div>< div class =comment>< strong> 2< / strong>< / div>< / body>'）
>>>> for div in soup.findAll（'div'，'comment'）：
... div.extract（）
...
< div class =comment> ; strong> 2< / strong>< / div>
>>>> soup
< body>< div> 1< / div>< / body&
how do you use python 2.6 to remove everything including the <div class="comment"> ....remove all ....</div>
i tried various way using re.sub without any success
Thank you
解决方案
This can be done easily and reliably using an HTML parser like BeautifulSoup:
>>> from BeautifulSoup import BeautifulSoup
>>> soup = BeautifulSoup('<body><div>1</div><div class="comment"><strong>2</strong></div></body>')
>>> for div in soup.findAll('div', 'comment'):
... div.extract()
...
<div class="comment"><strong>2</strong></div>
>>> soup
<body><div>1</div></body>
See this question for examples on why parsing HTML using regular expressions is a bad idea.
