Hi

just i modified your code and make it according to your need...

C#

{
            XmlDataSource oXmlDataSource = new XmlDataSource();
            oXmlDataSource.XPath = "siteMap/siteMapNode";
            XmlDocument doc = new XmlDocument();
            doc.Load(Server.MapPath(".") + "\\LoadRole.xml");
            XmlNode root = doc.DocumentElement;
            //  XmlNodeList nodeList = doc.SelectNodes("/RolesList/Roles[@ID=" + UserRole + "]");
            XmlNodeList nodeList = doc.SelectNodes("/RolesList/Roles[@ID=01]");

            drpUpdateRole.Items.Insert(0, new ListItem(string.Empty, string.Empty));
            List<ListItem> items = new List<ListItem>();

            foreach (XmlNode node in nodeList)
            {
                for (int i = 0; i < node.ChildNodes.Count; i++)
                {
                    string text = node.ChildNodes[i].InnerXml;
                    string xml = @"<Test>" + text + "</Test>";
                    XDocument doc2 = XDocument.Parse(xml);
                    //Get your wood nodes and values in a list 
                    List<Tuple<string, string>> list = doc2.Descendants().Select(a => new Tuple<string, string>(a.Name.LocalName, a.Value)).ToList();
                    items.Add(new ListItem(list[1].Item2, list[2].Item2));

                }

            }
            drpUpdateRole.Items.AddRange(items.ToArray());
        }
