问题描述
假设我有汤，我想删除所有段落的所有样式标签.因此，我想在整个汤中将<p style='blah' id='bla' class=...>更改为<p id='bla' class=...>.但是我不想触摸例如<img style='...'>标签.我该怎么办?
Let's say I have a soup and I'd like to remove all style tags for all the paragraphs. So I'd like to turn <p style='blah' id='bla' class=...> to <p id='bla' class=...> in the entire soup. But I don't want to touch, say, <img style='...'> tags. How would I do this?
推荐答案
想法是使用find_all('p')遍历所有p标签并删除样式属性:
The idea is to iterate over all p tags using find_all('p') and remove the style attribute:
from bs4 import BeautifulSoup
data = """
<body>
<p style='blah' id='bla1'>paragraph1</p>
<p style='blah' id='bla2'>paragraph2</p>
<p style='blah' id='bla3'>paragraph3</p>
<img style="awesome_image"/>
</body>"""
soup = BeautifulSoup(data, 'html.parser')
for p in soup.find_all('p'):
if 'style' in p.attrs:
del p.attrs['style']
print soup.prettify()
打印:
<body>
<p id="bla1">
paragraph1
</p>
<p id="bla2">
paragraph2
</p>
<p id="bla3">
paragraph3
</p>
<img style="awesome_image"/>
</body>
