我有一个谷歌应用引擎应用程序,我正在尝试使用 feedparser 来访问对提要的评论。我正在使用来自 Google 博客示例的提要进行测试

<?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'

        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, &quot;object has no attribute '%s'&quot; % key
AttributeError: object has no attribute 'thr_in'

如何访问评论及其任何属性?

谢谢

看起来点符号即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']

有效。

然而,点符号仍然适用于原子命名空间,即访问条目的 id,我仍然可以这样做

child.id
