Question

假设我有

text = """ <a href = 'http://www.crummy.com/software'>Hello There</a>"""

我想用一个空格（“”）替换一个hrefs和/ a。取而代之。 BTW它是一个BeautifulSoup.BeautifulSoup类。所以正常的.replace是行不通的。

我希望文字只是

""" Hello There """

注意“你好”之前和之后的空格。

Answer 1

您可以使用replaceWith()（或replace_with()）：

from bs4 import BeautifulSoup

soup = BeautifulSoup("""
<html>
 <body>
  <a href = 'http://www.crummy.com/software'>Hello There</a>
 </body>
</html>
""")

for a in soup.findAll('a'):
    a.replaceWith(" %s " % a.string)

print soup

打印：

<html><body>
 Hello There 
</body></html>

Answer 2

使用.replace_with()和.text属性：

>>> from bs4 import BeautifulSoup as BS
>>> text = """ <a href = 'http://www.crummy.com/software'>Hello There</a>"""
>>> soup = BS(text)
>>> mytag = soup.find('a')
>>> mytag.replace_with(mytag.text + ' ')
<a href="http://www.crummy.com/software">Hello There</a>
>>> print soup
 Hello There

Answer 3

 import re
 notag = re.sub("<.*?>", " ", html)
 >>> text = """ <a href = 'http://www.crummy.com/software'>Hello There</a>"""
 >>> notag = re.sub("<.*?>", " ", text)
 >>> notag
 '  Hello There '
