you might find program helpful:

from bs4 import beautifulsoup bs4.element import comment, navigablestring html_doc = 'x.html' soup = beautifulsoup(open(html_doc))  # identify start comment def isinstancebegineditable(text):     return (isinstance(text, comment) ,             text.strip().startswith("instancebegineditable"))  # identify end comment def isinstanceendeditable(text):     return (isinstance(text, comment) ,             text.strip().startswith("instanceendeditable"))  # start comments instancebegineditable in soup.find_all(text=isinstancebegineditable):     # found start comment, @ text , comments:     text in instancebegineditable.find_all_next(text=true):         # found text or comment, examine closely         if isinstanceendeditable(text):             # found end comment, out of pool             break         if isinstance(text, comment):             # found comment, ignore             continue         if not text.strip():             # found blank text, ignore             continue         # whatever left must         print text
