我会选择BeautifulSoup：

from bs4 import BeautifulSoup
from bs4.element import NavigableString
from copy import copy

def strip_content(in_tag):
    tag = copy(in_tag) # remove this line if you don't care about your input
    if tag.name == 'script':
        # Do no mess with scripts
        return tag
    # strip content from all children
    children = [strip_content(child) for child in tag.children if not isinstance(child, NavigableString)]
    # remove everything from the tag
    tag.clear()
    for child in children:
        # Add back stripped children
        tag.append(child)
    return tag

def test(filename):
    soup = BeautifulSoup(open(filename))
    cleaned_soup = strip_content(soup)
    print(cleaned_soup.prettify())

if __name__ == "__main__":
    test("myfile.html")
