Beautiful Soup 4: Remove comment tag and its content

The page that I’m scraping contains these HTML codes. How do I remove the comment tag <!-- --> along with its content with bs4?

<div class="foo">
cat dog sheep goat
<!-- 
<p>NewPP limit report
Preprocessor node count: 478/300000
Post‐expand include size: 4852/2097152 bytes
Template argument size: 870/2097152 bytes

</p>
-->
</div>

Answer

You can use extract() (solution is based on this answer):

PageElement.extract() removes a tag or string from the tree. It returns the tag or string that was extracted.

from bs4 import BeautifulSoup, Comment

data = """<div class="foo">
cat dog sheep goat
<!--
<p>test</p>
-->
</div>"""

soup = BeautifulSoup(data)

div = soup.find('div', class_='foo')
for element in div(text=lambda text: isinstance(text, Comment)):
    element.extract()

print soup.prettify()

As a result you get your div without comments:

<div class="foo">
    cat dog sheep goat
</div>
