Remove all html in python?

问题

Is there a way to remove/escape html tags using lxml.html and not beautifulsoup which has some xss issues? I tried using cleaner, but i want to remove all html.

回答1:

Try the .text_content() method on an element, probably best after using lxml.html.clean to get rid of unwanted content (script tags etc...). For example:

from lxml import html
from lxml.html.clean import clean_html

tree = html.parse('http://www.example.com')
tree = clean_html(tree)

text = tree.getroot().text_content()

I believe that, this code can help you:

from lxml.html.clean import Cleaner

html_text = "<html><head><title>Hello</title><body>Text</body></html>"
cleaner = Cleaner(allow_tags=[''], remove_unknown_tags=False)
cleaned_text = cleaner.clean_html(html_text)

This uses lxml's cleaning functions, but avoids the result being wrapped in an HTML element.

import lxml

doc = lxml.html.document_fromstring(str) 
cleaner = lxml.html.clean.Cleaner(allow_tags=[''], remove_unknown_tags=False)
str = cleaner.clean_html(doc).text_content()

or as a one liner

lxml.html.clean.Cleaner(allow_tags=[''], remove_unknown_tags=False).clean_html(lxml.html.document_fromstring(str)).text_content()

It works by providing parsing the html manually into a document object, and giving that to the cleaner class. That way clean_html also returns an object rather than a string. Then the text can be recovered without a wrapper element using text_content() method.
