I an not able to read data that has Poll in the prefix of the element tag.

foreach (XmlNode RSSNode in RSSChannelItemList)

        {

            XmlNode RSSSubNode;

            RSSSubNode = RSSNode.SelectSingleNode("title");

            string title = RSSSubNode != null ? RSSSubNode.InnerText : "";

            XNamespace Tips = "http://www.example.com";

            RSSSubNode = RSSNode.SelectSingleNode("ID");

            string link = RSSSubNode != null ? RSSSubNode.InnerText : "";

            link = RSSSubNode!=null ? RSSSubNode.InnerXml : "";

        }

I get the title value perfectly but I am unable to get the value of ID This is a custom tag in the XMl

Can anyone suggest me How to do this?

    Hi Chintoo, 


    try this:

    XmlNamespaceManager nameSpace = new XmlNamespaceManager(doc.NameTable);

         nameSpace.AddNamespace("Tips", "http://www.example.com");

         RSSSubNode = RSSNode.SelectSingleNode("Tips:ID",nameSpace);

         string link = RSSSubNode != null ? RSSSubNode.InnerText : "";
