How to generate an RSS feed for your web site using ASP.NET

How to generate an RSS feed for your web site using ASP.NET

 

RSS stands for "Really Simple Syndication", is a standardized, XML-formatted means for syndication Web site content.

Understand that RSS is intended to provide information about a Web site's latest content. For example, Yahoo! News provides RSS feeds of the latest news headlines, and TigerDirect.com provides RSS feeds of the feature items on the shopping site. Notice that RSS provides a synopsis for the recent articles or news items. It does not provide the complete content for all of the news items or articles.

 

Let’s look at a demo RSS feed XML file: (Excerpted from the reference URL.)

<?xml version="1.0" encoding="utf-8"?>

<rss version="2.0">

       <channel>

              <title>uberASP.Net NewsWire</title>

              <link>http://www.uberasp.net/newswire.aspx</link>

              <description>The latest headlines and articles from the world of ASP.NET, Microsoft's Web development platform.</description>

Brief introduction to RSS 2.0 speficiation:

The root element of an RSS document is <rss>. It has precisely one child element, <channel>. The <channel> element contains information about the syndicated content, as well as information about each content item being syndicated. There are three required channel elements:

l         <title> - provides a title for the channel.

l         <link> - a URL to the channel.

l         <description> - a short description of the channel.

There are additional optional elements, such as <language>, <copyright>, <webMaster>, and others. For a complete list refer to the RSS 2.0 specification.

 

The next important part of the spec is what you put in each item. The only thing required here is the title or description. We're using both, plus a link back to the article (because we want people to read the entire story, duh), and the pubDate element so the end-user can see how new the headline is.
