python的items不是迭代器_“list”对象在Python的beauthulsoup renderContents中没有属性“items”...

为了从输入中删除不需要的/不安全的标记和属性，我使用了以下代码(几乎完全是通过http://djangosnippets.org/snippets/1655/)：def html_filter(value, allowed_tags = 'p h1 h2 h3 div span a:href:title img:src:alt:title table:cellspacing:cellpadding th tr td:colspan:rowspan ol ul li br'):

js_regex = re.compile(r'[s]*(.{1,7})?'.join(list('javascript')))

allowed_tags = [tag.split(':') for tag in allowed_tags.split()]

allowed_tags = dict((tag[0], tag[1:]) for tag in allowed_tags)

soup = BeautifulSoup(value)

for comment in soup.findAll(text=lambda text: isinstance(text, Comment)):

comment.extract()

for tag in soup.findAll(True):

if tag.name not in allowed_tags:

tag.hidden = True

else:

tag.attrs = [(attr, js_regex.sub('', val)) for attr, val in tag.attrs.items() if attr in allowed_tags[tag.name]]

return soup.renderContents().decode('utf8')

它适用于不需要的或白名单上的标签，没有白名单的属性，甚至是格式不好的html。但是，如果列出了任何白色属性，则会引发

^{pr2}$

最后一行，对我没什么帮助。type(soup)是{}它是否引发错误，所以我不知道它指的是什么。在Traceback:
