[VS 2005] RSS 404 error problems

[§tudz]

Hi,

I'm trying to learn how to deal with RSS feeds, I'm just querying the BBC's weatherfeed at the momement.

I am trying to detect if the feed is there or not, if not I just want it to write to the console "feed NOT available"

I've added some code to check for the Error 404, but it doesnt work, I still end up getting an error.

And ideas?

Cheers,

My CODE:

       public class WeatherChecker
    {
        
        public void getCountries()
        {
            string server = "http://feeds.bbc.co.uk/weather/feeds/rss/5day/world/";
            int i = 0;

            bool XMLReturned = true;
            DataSet ds_XML = new DataSet();

            do
            {
                i++;
                string citycode = i.ToString("0000");

                try
                {
                    ds_XML.ReadXml(server + citycode + ".xml");

                    //Send Response
                    HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(server + citycode + ".xml");

                    webRequest.AllowAutoRedirect = false; // In case the server is configured to redirect on 404


                    //Get Result
                    HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();

                    if (webResponse.StatusCode != HttpStatusCode.OK)
                    {
                        Console.Out.WriteLine("feed NOT available");

                     }
                     else
                     {
                         Console.Out.WriteLine(" ");
                         Console.Out.WriteLine("feed IS available");

                         StreamReader WeatherStream = new StreamReader(webResponse.GetResponseStream());

                         ds_XML.ReadXml(WeatherStream);

                         string strTitle = ds_XML.Tables["channel"].Rows[0]["title"].ToString();

                         if (ds_XML.Tables.Count > 0)
                         {
                             string TitleParts = strTitle.Replace("BBC - Weather Centre - Forecast for","");
                             string[] City = TitleParts.Split(',');
                            
                             XMLReturned = true;

                             Console.Out.WriteLine(citycode + " - " + City[0]);
                             ds_XML.Clear();
                         }
                         else
                         {
                             XMLReturned = false;
                         }
                        
                     }


  

            }
                catch (Exception er)
                {
                    Console.Out.WriteLine(er);
                }
            }
            while (XMLReturned == true);

        }

    }
