What steps will reproduce the problem?
from html5lib import HTMLParser from html5lib.treebuilders import getTreeBuilder from html5lib.treewalkers import getTreeWalker from html5lib.filters.sanitizer import Filter as Sanitizer html = "<html><body><h1>Header" parser = HTMLParser(tree = getTreeBuilder("lxml"), namespaceHTMLElements = False) doc = parser.parse(html) root = doc.getroot() body = doc.xpath('/html/body') walker = getTreeWalker('lxml') stream = walker(body) stream = Sanitizer(stream) for token in stream: print tokenWhat is the expected output? What do you see instead?
I do not know exactly what should be printed. Instead, an exception is raised:
$ python t.py {'namespace': u'None', 'type': 'Characters', 'data': u'<body>'} Traceback (most recent call last): File "t.py", line 17, in <module> for token in stream: File "/home/radek/.virtualenvs/blog/local/lib/python2.7/site-packages/html5lib-0.95-py2.7.egg/html5lib/filters/sanitizer.py", line 7, in __iter__ token = self.sanitize_token(token) File "/home/radek/.virtualenvs/blog/local/lib/python2.7/site-packages/html5lib-0.95-py2.7.egg/html5lib/sanitizer.py", line 171, in sanitize_token token["data"][::-1] TypeError: unhashable typePlease provide any additional information below.
the faulty token is:
{'namespace': u'None ',' type ':' StartTag ',' name ': u'h1', 'data': {}}
