A column named '/' already belongs to this DataTable

WebRequest request=WebRequest.Create("your url");
WebReponse response=request.GetRespose();

2) Create a XML document and load the XML document with stream from response object:

Stream rssStream=response.GetResponseStream();
XMLDocument xmlDoc=new XMLDocument();
xmlDoc.Load(rssStream);

3)Retrieve matching XML nodes from XMLDocument with XMLNodeList:

XmlNodeList xmlNodeList = xmlDoc.SelectNodes("your XPath expression");

4) Now you can loop the RSS feed items to get what you want:

for (int i = 0; i < xmlNodeList.Count; i++)
{
    XmlNode xmlNode;

    xmlNode = xmlNodeList.Item(i).SelectSingleNode("ProductName");
    //xmlNode.InnerText;
}

thanks for your prompt answer !!

this is quite a different approach to what is proposed in the sample code you can find below

http://www.aspsnippets.com/Articles/Fetch-and-Display-RSS-Feeds-using-ASP.Net.aspx

what modifications are needed to implement the loop approach you are suggesting in this code instead of using the repeater on the markup area of the asp.net web form ?

Hi,

You probably have a corporate proxy, try using this in the web.config:

<system.net>
  <defaultProxy useDefaultCredentials="true" />
</system.net>

As for the 1st problem:

The issue is likely because XML will allow duplicate nodes and a data table will not allow duplicate columns, so you cannot parse directly to a data table.

I would suggest doing some research into parsing and using XML data before going to far down the data table route

thanks Makar, that makes absolute sense !!

do you have the code I should use in order to parse into XML instead of the data table and then display it into the repeater ?
