我目前正在从文本中删除一些HTML，如下所示：
<p><b>Masala</b> films of <a href="/wiki/Cinema_of_India" title="Cinema of India">Indian cinema</a> are those that mix genres in one work. Typically these films freely mix <a href="/wiki/Action_film" title="Action film">action</a>, <a href="/wiki/Comedy_film" title="Comedy film">comedy</a>, <a href="/wiki/Romance_film" title="Romance film">romance</a>, and <a href="/wiki/Drama_film" title="Drama film">drama</a> or <a href="/wiki/Melodrama" title="Melodrama">melodrama</a>.<sup class="reference" id="cite_ref-Ganti2004_1-0"><a href="#cite_note-Ganti2004-1"><span>[</span>1<span>]</span></a></sup> They tend to be <a href="/wiki/Musical_film" title="Musical film">musicals</a> that include songs filmed in picturesque locations.

我使用的剥离器代码如下：
from HTMLParser import HTMLParser
class MLStripper(HTMLParser):
def __init__(self):
self.reset()
self.fed = []
def handle_data(self, d):
self.fed.append(d)
def get_data(self):
return ''.join(self.fed)
def strip_tags(html):
s = MLStripper()
print html
s.feed(html)
return s.get_data()
当我试图删除上面的段落时，我似乎遇到了一些问题：
para = strip_tags(paragraph)
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-97-0f8917286c8e> in <module>()
2 for key, val in film_links.items():
3 paragraph = get_description_from_url( val, key)
----> 4 para = strip_tags(paragraph)
5 film_genre_with_des.append([key, val, para])
<ipython-input-91-0c0e68f587c6> in strip_tags(html)
13 s = MLStripper()
14 print html
---> 15 s.feed(html)
16 return s.get_data()
/Users/ruby/anaconda/lib/python2.7/HTMLParser.pyc in feed(self, data)
114 as you want (may include '\n').
115 """
--> 116 self.rawdata = self.rawdata + data
117 self.goahead(0)
118
TypeError: cannot concatenate 'str' and 'Tag' objects
不太确定为什么这不起作用。这适用于Python 2.7，这是我正在使用的版本。

或者，您可以使用BeautifulSoup HTML parser，只需使用get the text：
from bs4 import BeautifulSoup

Masala films of Indian cinema are those that mix genres in one work. Typically these films freely mix action, comedy, romance, and drama or melodrama.[1] They tend to be musicals that include songs filmed in picturesque locations. The genre is named after the masala, a mixture of spices in Indian cuisine.[2] According to The Hindu, masala is the most popular genre of Indian cinema.[3]
