Question

I’m using RSS.NET for .NET 2.0. Try as I might, I get 0 channels for the following:

feed = RssFeed.Read("http://feeds.feedburner.com/punchfire?format=xml");

I note that for other feeds this works e.g.

feed = RssFeed.Read("http://www.engadget.com/rss.xml");

I guess it has to be a valid xml document. Do you think I should check for “.xml” in my application code or is there any way to tweak RSS.NET into accepting feedburner feeds?

Answer 1

The reason you are not able to get any channel nodes is that, atom format doesn’t have any channel nodes. check following

• The Atom Syndication Format

Your second link is an Rss Feed, which contains channel node like as follows

<rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd">
<channel>
<title>Engadget</title>
<link>http://www.engadget.com</link>
 .
 .
 .

On the other hand an atom feed does not use channel nodes, as you might understand by following specification link above.

<?xml version="1.0" encoding="utf-8"?>
   <feed xmlns="http://www.w3.org/2005/Atom">
     <title type="text">dive into mark</title>
     <subtitle type="html">
       A &lt;em&gt;lot&lt;/em&gt; of effort
       went into making this effortless
     </subtitle>

     <link rel="alternate" type="text/html"
      hreflang="en" href="http://example.org/"/>
     <link rel="self" type="application/atom+xml"
      href="http://example.org/feed.atom"/>

     <entry>
      .
      .
      .

EDIT: To check feed Format

    // url of the feed 
    string utlToload = @"http://feeds.feedburner.com/punchfire?format=xml"



    // load feed
        Argotic.Syndication.GenericSyndicationFeed feed = 
Argotic.Syndication.GenericSyndicationFeed.Create(new Uri(urlToLoad));

        // check what format is it
        if (feed.Format.Equals(SyndicationContentFormat.Rss))
        {
            // yourlogic here
        }
        else if (feed.Format.Equals(SyndicationContentFormat.Atom))
        {
            // yourlogic here
        } 
        else if (feed.Format.Equals(SyndicationContentFormat.NewsML))
        {
            // yourlogic here
        } 

Hope it helps
