XmlDocument doc = new XmlDocument();
           doc.Load("D://gokul/projects/New Folder/xmltree/xmltree/tree.xml");
           string tag = txttag.Text;
            string val = txtval.Text;
            XmlNodeList lis = doc.SelectNodes("//ContentNode[@name]");
            t = TreeView1.SelectedNode.Text;
           TreeNode nd=TreeView1.SelectedNode;
           XmlAttribute attr = doc.CreateAttribute(tag);
           attr.Value = val;
           foreach (XmlNode n in lis)
           {
               string attrVal = n.Attributes["name"].Value;
               XmlNode atlst = n.ChildNodes.Item(0);
               if (t==attrVal )
               {

                   n.Attributes.Append(attr);

                   doc.Save("D:/gokul/projects/New Folder/xmltree/xmltree/tree.xml");
               }}

这将从两个txt框中读取值，并获取TAG及其值的值.然后它将特定的属性添加到选定的节点.

this will read the values from two txt boxes and get the values for TAG and its VALUE. and then it ll add that particular attribute to the node which is selected.
