How can I strip comment tags from HTML using BeautifulSoup?

by

Straight from the documentation for BeautifulSoup, you can easily strip comments (or anything) using extract():

from BeautifulSoup import BeautifulSoup, Comment
soup = BeautifulSoup("""1<!--The loneliest number-->
                        <a>2<!--Can be as bad as one--><b>3""")
comments = soup.findAll(text=lambda text:isinstance(text, Comment))
[comment.extract() for comment in comments]
print soup
# 1
# <a>2<b>3</b></a>
