Feedparser is not sanitizing html text downloaded via asyncio aiohttp

Question

• I am downloading feed using aiohttp asyncio
• Feedparser is supposed to sanitize input text with its _HTMLSanitizer class to accept only specific tags

The sanitizer does not work, any suggestions?

import aiohttp
import asyncio
import feedparser

feedparser._HTMLSanitizer.acceptable_elements = ['a', 'img']
feedparser._HTMLSanitizer.acceptable_css_keywords = []
feedparser._HTMLSanitizer.acceptable_css_properties = []
feedparser._HTMLSanitizer.acceptable_svg_properties = []
feedparser._HTMLSanitizer.acceptable_attributes = ['href', 'src']

async def load_feed():
  async with aiohttp.ClientSession() as session:
    async with session.get('http://zycrypto.com/feed') as response:
      text = await response.text()
      parsed = feedparser.parse(text)
      for entry in parsed.entries:
        print(entry.title)
        print(entry.summary, '\n\n')


asyncio.get_event_loop().run_until_complete(load_feed())

Current Output

The only thing that remains crystal clear is the fact that only the strongest will survive in the long-term. In the crypto space, Ripple’s XRP will be one of the very few cryptocurrencies that will stand the test of time. This is according to Dan Morehead, [&#8230;]
