我解析使用feedparser這個文件。我做到以下幾點：

import feedparser 
text = "" #Read from the above document 
d = feedparser.parse(text) 
d.entries[0].issues_label

我觀察，我得到的只是一個標籤：

d.entries[0].issues_label 
u'Action-ReductionNeeded'

有多種問題標籤：

<issues:label>Type-Bug</issues:label><issues:label>Pri-2</issues:label><issues:label>OS-All</issues:label><issues:label>Area-Compat</issues:label><issues:label>Webkit-specific</issues:label><issues:label>Mstone-2.1</issues:label><issues:label>compat-bug-2.0</issues:label><issues:label>Report-to-webkit</issues:label><issues:label>bulkmove</issues:label><issues:label>Action-ReductionNeeded</issues:label>

，但我能夠檢索剛剛過去一。我想檢索所有這些。

您可以用lxml而不是解析XML：

>>> import lxml.etree 
>>> doc = lxml.etree.parse(xml) 
>>> ns = {'issues':'http://schemas.google.com/projecthosting/issues/2009'} 
>>> [x.text for x in doc.xpath('//issues:label', namespaces=ns)] 
<<< 
['Type-Bug', 
'Pri-2', 
'OS-All', 
'Area-Compat', 
'Webkit-specific', 
'Mstone-2.1', 
'compat-bug-2.0', 
'Report-to-webkit', 
'bulkmove', 
'Action-ReductionNeeded']
