Answer 1

您可能会发现此计划很有用：

from bs4 import BeautifulSoup
from bs4.element import Comment, NavigableString
html_doc = 'x.html'
soup = BeautifulSoup(open(html_doc))

# Identify the start comment
def isInstanceBeginEditable(text):
    return (isinstance(text, Comment) and
            text.strip().startswith("InstanceBeginEditable"))

# Identify the end comment
def isInstanceEndEditable(text):
    return (isinstance(text, Comment) and
            text.strip().startswith("InstanceEndEditable"))

# Look for start comments
for instanceBeginEditable in soup.find_all(text=isInstanceBeginEditable):
    # We found a start comment, look at all text and comments:
    for text in instanceBeginEditable.find_all_next(text=True):
        # We found a text or comment, examine it closely
        if isInstanceEndEditable(text):
            # We found the end comment, everybody out of the pool
            break
        if isinstance(text, Comment):
            # We found a comment, ignore
            continue
        if not text.strip():
            # We found a blank text, ignore
            continue
        # Whatever is left must be good
        print text

Answer 2

import bs4
soup = bs4.BeautifulSoup(html_text)
soup.get_text().replace('\n','')
