python - 如何在html中使用正则表达式或其他方式在python中删除标签下的属性？

Question

我用这段代码来保存 <p>和 <br>字符串中的标记。

from bs4 import BeautifulSoup

mystring = 'aaa<p>Radio and<BR> television.<br></p><p align="right">very<br/> popular in the world today.</p><p class="myclass">Millions of people watch TV. </p><p>That’s because a radio is very small <span style=":_black;">98.2%</span></p><p>and it‘s easy to carry. <span style=":_black;">haha100%</span></p>bb'
soup = BeautifulSoup(mystring,'html.parser')
for e in soup.find_all():
    if e.name not in ['p','br']:
        e.unwrap()
print(str(soup))

结果是:

aaa<p>Radio and<br/> television.<br/></p><p align="right">very<br> popular in the world today.</br></p><p class="myclass">Millions of people watch TV. </p><p>That’s because a radio is very small 98.2%</p><p>and it‘s easy to carry. haha100%</p>bb

但是我发现<p>下面还有一些属性标签。例如，对齐和分类。事实上，我想删除align="right"和 class="myclass"和 <p> 中的其他属性标签，保留<p>即可标签。

我想要这样的结果:

aaa<p>Radio and<br/> television.<br/></p><p>very<br> popular in the world today.</br></p><p>Millions of people watch TV. </p><p>That’s because a radio is very small 98.2%</p><p>and it‘s easy to carry. haha100%</p>bb

我要删除<p>下的属性标签。

如何做到这一点？

你的意思是:

for e in soup.find_all():
    if e.name not in ['p','br']:
        e.unwrap()
    else:
        e.attrs={}
print(str(soup))
