Publish to RSS from command line

From a Windows command line, I'd like to be able to publish to an RSS feed. I visualize something like this:

rsspub @builds "Build completed without errors."

Then, someone could go to my computer:

http://xp64-Matt:9090/builds/rss.xml

And there'd be a new entry with the date and time and the simple text "Build completed without errors."

I'd like the feed itself to run on a different port, so I'm not fighting with IIS or Apache, or whatever else I need to run on my computer on a day-to-day basis.

Does anything like this exist?

• Here's a simple .Net 3.5 C# program that will create an RSS XML file that you can store in your IIS webroot:

  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Text;
  using System.Xml;
  using System.IO;
  
  namespace CommandLineRSS
  {
      class Program
      {
       static void Main( string[] args )
       {
        var file = args[ 0 ];
        var newEntry = args[ 1 ];
  
        var xml = new XmlDocument();
  
        if ( File.Exists( file ) )
         xml.Load( file );
        else
         xml.LoadXml( @"<rss version='2.0'><channel /></rss>" );
  
        var xmlNewEntry = Create( (XmlElement)xml.SelectSingleNode( "/rss/channel" ), "item" );
        Create( xmlNewEntry, "title" ).InnerText = newEntry;
        Create( xmlNewEntry, "pubDate" ).InnerText = DateTime.Now.ToString("R");
  
        xml.Save( file );
       }
  
       private static XmlElement Create( XmlElement parent, string tag )
       {
        var a = parent.OwnerDocument.CreateElement( tag );
        parent.AppendChild( a );
        return a;
       }
      }
  }
  

  Then you can call it like this:

  CommandLineRSS.exe c:\inetpub\wwwroot\builds.xml "Build completed with errors."
