困惑中的Atom feed命名空间 [英] Confused about namespaces in Atom feed

问题描述

有

有什么区别

 ＆LT; OpenSearch的：totalResults＆GT; 1000℃; / OpenSearch的：totalResults＆GT;
 

和

 ＆LT; totalResults的xmlns =OpenSearch的＆GT; 1000℃; / totalResults＆GT;
 

我使用SyndicationFeed类在.NET中生成一个Atom feed，我需要添加一些元素的OpenSearch的标准，但它一直像后者添加元素时，我想它来增加他们像上述前者。

在code：

  feed.ElementExtensions.Add（totalResults，OpenSearch的，2）;
 

修改

根饲料标签看起来像这样

 ＆LT;饲料XML：LANG =EN-USP1：OpenSearch的=htt​​p://a9.com/-/spec/opensearch/1.1/的xmlns：P1 = 的xmlns的xmlns =htt​​p://www.w3.org/2005/Atom＆GT;
 

改变我的code作为@Reddog建议后，totalresults元素看起来像这样

 ＆LT; totalResults的xmlns =htt​​p://a9.com/-/spec/opensearch/1.1/＆GT; 1000℃; / totalResults＆GT;
 

在code，增加了空间的饲料标签看起来像这样

  feed.AttributeExtensions.Add（
    新XmlQualifiedName（OpenSearch的，的xmlns），
    @http://a9.com/-/spec/opensearch/1.1/）;
 

而code，现在增加了totalresults元素看起来像这样

  feed.ElementExtensions.Add（totalResults，@http://a9.com/-/spec/opensearch/1.1/，1000）;
 

解决方案

没关系。我意识到，我被错误地添加的命名空间。它应该是

  feed.AttributeExtensions.Add（
   新XmlQualifiedName（OpenSearch的，http://www.w3.org/2000/xmlns/），
   http://a9.com/-/spec/opensearch/1.1/）;
 

Is there any difference between

<opensearch:totalResults>1000</opensearch:totalResults>

and

<totalResults xmlns="opensearch">1000</totalResults>

I'm using the SyndicationFeed class in .NET to generate an Atom feed, and I need to add some elements for the opensearch standard, but it keeps adding elements like the latter one above when I want it to add them like the former one.

The code:

feed.ElementExtensions.Add("totalResults", "opensearch", "2");

EDIT

The root feed tag looks like this

<feed xml:lang="en-US" p1:opensearch="http://a9.com/-/spec/opensearch/1.1/" xmlns:p1="xmlns" xmlns="http://www.w3.org/2005/Atom">

After changing my code as @Reddog suggested, the totalresults element looks like this

<totalResults xmlns="http://a9.com/-/spec/opensearch/1.1/">1000</totalResults>

The code that adds the namespace to the feed tag looks like this

feed.AttributeExtensions.Add(
    new XmlQualifiedName("opensearch", "xmlns"),
    @"http://a9.com/-/spec/opensearch/1.1/");

And the code that adds the totalresults element now looks like this

feed.ElementExtensions.Add("totalResults", @"http://a9.com/-/spec/opensearch/1.1/", "1000");

解决方案

Nevermind. I realized that I was adding the namespace incorrectly. It should be

feed.AttributeExtensions.Add(
   new XmlQualifiedName("opensearch", "http://www.w3.org/2000/xmlns/"),
   "http://a9.com/-/spec/opensearch/1.1/");
