SyndicationFeed内容：编码 [英] SyndicationFeed content:encoded

问题描述

I&rsquo的，M使用 SyndicationFeed 类消耗一定的RSS源。我想知道如何获得内容：一个RSS feed的编码节点。这是I&rsquo的代码，M使用：

I’m using the SyndicationFeed class to consume some rss feeds. I am wondering how to get the content:encoded node of an RSS feed. This is the code I’m using:

XmlReader reader = XmlReader.Create(response.GetResponseStream());

SyndicationFeed feed = SyndicationFeed.Load(reader);

foreach (SyndicationItem item in feed.Items)
{
     string title = (item.Title != null) ? item.Title.Text : String.Empty;

     string content = ??

     string pubDate = (item.PublishDate != null) ? item.PublishDate.ToString("r") : String.Empty;

}

我可以使用 item.Summary的.text 但似乎返回说明节点，它可以只是一个简短的总结，而内容：编码将拥有的全部内容。有&rsquo的; S为 item.content 一种选择，但我不知道如何使用它和文档是稀缺的。

I can use item.Summary.Text but that seems to return the Description node, which can be just a short summary, while content:encoded will have the full content. There’s an option for item.content, but I'm not sure how to use it and documentation is scarce.

推荐答案

试试这个：

StringBuilder sb = new StringBuilder();
foreach (SyndicationElementExtension extension in item.ElementExtensions)
    {
         XElement ele = extension.GetObject<XElement>();
         if (ele.Name.LocalName == "encoded" && ele.Name.Namespace.ToString().Contains("content"))
         {
              sb.Append(ele.Value + "<br/>");
         }
    }
