使用feedparser访问注释

Question

我有一个Google应用程序引擎应用程序，我正在尝试使用feedparser来访问提要上的评论。我正在使用Google blogger示例中的提要进行测试

<?xml version='1.0' encoding='utf-8'?>
<?xml-stylesheet href="http://www.blogger.com/styles/atom.css" type="text/css"?>
<feed xmlns='http://www.w3.org/2005/Atom'
   xmlns:openSearch='http://a9.com/-/spec/opensearch/1.1/'
   xmlns:gd='http://schemas.google.com/g/2005'
   gd:etag='W/"CUYMQ348fyp7ImA9WB9UFkU."'>

        href='http://blogName.blogspot.com/2007/12/quite-disagreeable_5283.html'
        ref='tag:blogger.com,1999:blog-blogID.post-postID'
        source='http://www.blogger.com/feeds/blogID/posts/default/postID'
        type='text/html' />
  </entry>

目前，我的代码有

d= feedparser.parse(feedurl)
for child in d.entries:
   _url = child.thr_in-reply-to.href

我收到错误消息

raise AttributeError, "object has no attribute '%s'" % key
AttributeError: object has no attribute 'thr_in'

如何访问注释及其任何属性？

谢谢

Answer 1

它看起来像是点符号，即child.thr_in-reply-to.href不适用于其他名称空间。当我将其更改为

child['thr_in-reply-to']['href']

啊，真灵。

但是，点符号仍然适用于atom名称空间，即访问条目的id，我仍然能够这样做

child.id
