如何获取XML标签django的CDATA内容

I am using urllib and beautifulsoup to parse xml file in django. I can't parse the content of description tag with CDATA.

我正在使用urllib和beautifulsoup来解析django中的xml文件。我无法用CDATA解析description标记的内容。

my xml tag.

我的xml标签。

<item>
         <title>EU Confronting US Over Surveillance</title>
    <description><![CDATA[Voice of America is an international news and broadcast organization serving Central and Eastern Europe, the Caucasus, Central Asia, Russia, the Middle East and Balkan countries]]></description>
<guid>http://www.voanews.com/content/eu-confronting-us-over-surveillance/1778928.html</guid>
</item>

This description tag is inside the item tag views.py

此描述标记位于项目标记views.py中

for i in soup.findAll('item'):
 print i.description.string

If CDATA is not there means I can parse the contents inside descirption tag. I don't know how to parse this content. Please help me out Also how to get the image inside the tag..

如果CDATA不存在意味着我可以解析descirption标签内的内容。我不知道如何解析这个内容。请帮帮我以及如何获取标签内的图像..

CData can be accessed like this:

可以像这样访问CData:

>>> import BeautifulSoup
>>> txt = '''<description><![CDATA[Voice of America is an international news and broadcast organization serving Central and Eastern Europe, the Caucasus, Central Asia, Russia, the Middle East and Balkan countries]]></description>'''
>>> soup = BeautifulSoup.BeautifulSoup(txt)
>>> for cd in soup.findAll(text=True):
...   if isinstance(cd, BeautifulSoup.CData):
...     print 'CData value: %r' % cd
...
CData value: u'Voice of America is an international news and broadcast organi
zation serving Central and Eastern Europe, the Caucasus, Central Asia, Russia, t
he Middle East and Balkan countries'
>>>

from bs4 import BeautifulSoup, CData
import urllib

source_txt = urllib.urlopen("http://voanews.com/api/epiqq")
soup = BeautifulSoup.BeautifulSoup(source_txt.read())
for cd in soup.findAll(text=True):
    if isinstance(cd, CData):
        print 'CData value: %r' % cd

Things to note:

注意事项:

The import statement. I'm importing the entire BeautifulSoup package

进口声明。我正在导入整个BeautifulSoup包

The urlopen parameter. It needs the http
