Comment #1 on issue 183 by akvadr...@gmail.com: HTMLSanitizer can't be used
as a tokenizer
http://code.google.com/p/html5lib/issues/detail?id=183
This is a workaround and slightly safer design. There is no need for the
mixin or to hardcode the __init__ arguments:
from html5lib import HTMLParser
from html5lib.tokenizer import HTMLTokenizer
from html5lib.sanitizer import HTMLSanitizerMixin
from cgi import escape
class Sanitizer(HTMLTokenizer):
def __init__(self, *a, **kw):
HTMLTokenizer.__init__(self, *a, **kw)
self._saner = HTMLSanitizerMixin()
def __iter__(self):
for token in HTMLTokenizer.__iter__(self):
saner = self._saner.sanitize_token(token)
if saner: yield saner
PARSER = HTMLParser(tokenizer=Sanitizer)
def sanitize(html):
return PARSER.parseFragment(html).toxml()
