I have written this code but it is not giving required output. It is almost 99% correct. To get emailID I am getting XmlDocument xmlDoc = new XmlDocument(); if (File.Exists(filePath)) { xmlDoc.Load(filePath); XmlNodeList userNodes = xmlDoc.SelectNodes("//userSettings/Calc.Properties.Settings"); foreach (XmlNode userNode in userNodes) { XmlNode newSub1 = xmlDoc.CreateNode(XmlNodeType.Element, "setting", null); XmlAttribute xa1 = xmlDoc.CreateAttribute("name"); xa1.Value = "TableForeground"; XmlAttribute xb1 = xmlDoc.CreateAttribute("serializeAs"); xb1.Value = "String"; XmlNode newInnerSub1 = xmlDoc.CreateNode(XmlNodeType.Element, "value", tblForeground); newSub1.Attributes.Append(xa1); newSub1.Attributes.Append(xb1); userNode.AppendChild(newSub1); newSub1.AppendChild(newInnerSub1); XmlNode newSub2 = xmlDoc.CreateNode(XmlNodeType.Element, "setting", null); XmlAttribute xa2 = xmlDoc.CreateAttribute("name"); xa2.Value = "EmailID"; XmlAttribute xb2 = xmlDoc.CreateAttribute("serializeAs"); xb2.Value = "String"; XmlNode newInnerSub2 = xmlDoc.CreateNode(XmlNodeType.Element, "value", emialID); newSub2.Attributes.Append(xa2); newSub2.Attributes.Append(xb2); userNode.AppendChild(newSub2); newSub2.AppendChild(newInnerSub2); } xmlDoc.Save(filePath); }
