BeautifulSoup 保留一些文本，但删除标签的其余部分

Question

我正在使用一个从论坛抓取数据的机器人。我这里有这个可以使用：<description><![CDATA[ <p>This is a test post with a few emotes <img src="https://sjc5.discourse-cdn.com/try/images/emoji/twitter/grin.png?v=9" title=":grin:" class="emoji" alt=":grin:"> <img src="https://sjc5.discourse-cdn.com/try/images/emoji/twitter/heart.png?v=9" title=":heart:" class="emoji" alt=":heart:"></p> ]]></description>从此我想得到This is a test post with a few emotes :grin: :heart:我该怎么做呢？如果表情也位于文本中间，我也希望能够做到这一点。

Answer 1

from bs4 import BeautifulSoup, CData

txt = '''<description><![CDATA[ <p>This is a test post with a few emotes <img src="https://sjc5.discourse-cdn.com/try/images/emoji/twitter/grin.png?v=9" title=":grin:" class="emoji" alt=":grin:"> <img src="https://sjc5.discourse-cdn.com/try/images/emoji/twitter/heart.png?v=9" title=":heart:" class="emoji" alt=":heart:"></p> ]]></description>'''

# load main soup:

soup = BeautifulSoup(txt, 'html.parser')

# find CDATA inside <description>, make new soup

soup2 = BeautifulSoup(soup.find('description').find(text=lambda t: isinstance(t, CData)), 'html.parser')

# replace <img> with their alt=...

for img in soup2.select('img'):

    img.replace_with(img['alt'])

# print text

print(soup2.p.text)
