如何在文本中用标签的值替换标签

Question

How do I extract

I love Python

from given HTML

I <img src="image.png" alt="love"> Python

Getting string and splitting it won't work, text is controlled by user and might contain <>

Answer 1

There are a few different ways to achieve that. One way to do that would be to find all img elements and replace them with a text node containing the alt value of the img element:

In [1]: from bs4 import BeautifulSoup

In [2]: data = """<div class="commentthread_comment_text">I <img src="image.png" alt="love"> Python</div>"""

In [3]: soup = BeautifulSoup(data, "html.parser")

In [4]: div = soup.find('div', {'class': 'commentthread_comment_text'})

In [5]: for img in div('img'):
    ...:     img.replace_with(img['alt'])
    ...:     

In [6]: div.get_text()
Out[6]: 'I love Python'
