美丽的汤和 uTidy
我想将 utidy 的结果传递给 Beautiful Soup，ala：
page = urllib2.urlopen(url)
options = dict(output_xhtml=1,add_xml_decl=0,indent=1,tidy_mark=0)
cleaned_html = tidy.parseString(page.read(), **options)
soup = BeautifulSoup(cleaned_html)
运行时，出现以下错误结果：
Traceback (most recent call last):
File "soup.py", line 34, in <module>
soup = BeautifulSoup(cleaned_html)
File "/var/lib/python-support/python2.6/BeautifulSoup.py", line 1499, in __init__
BeautifulStoneSoup.__init__(self, *args, **kwargs)
File "/var/lib/python-support/python2.6/BeautifulSoup.py", line 1230, in __init__
self._feed(isHTML=isHTML)
File "/var/lib/python-support/python2.6/BeautifulSoup.py", line 1245, in _feed
smartQuotesTo=self.smartQuotesTo, isHTML=isHTML)
File "/var/lib/python-support/python2.6/BeautifulSoup.py", line 1751, in __init__
self._detectEncoding(markup, isHTML)
File "/var/lib/python-support/python2.6/BeautifulSoup.py", line 1899, in _detectEncoding
xml_encoding_match = re.compile(xml_encoding_re).match(xml_data)
TypeError: expected string or buffer
I Gather utidy 返回一个 XML 文档，而 BeautifulSoup 需要一个字符串。 有没有办法投射cleaned_html？ 或者我做错了，应该采取不同的方法？

When run, the following error results:

I gather utidy returns an XML document while BeautifulSoup wants a string. Is there a way to cast cleaned_html? Or am I doing it wrong and should take a different approach?

只需将
str()包裹在cleaned_html 上将其传递给 BeautifulSoup 时。
Just wrap
str()aroundcleaned_htmlwhen passing it to BeautifulSoup.
将传递给 BeautifulSoup 的值转换为字符串。
对于您的情况，请对最后一行进行以下编辑：
Convert the value passed to BeautifulSoup into a string.
In your case, do the following edit to the last line:
