newSub1.Attributes.Append(xa1);

newSub1.Attributes.Append(xb1);

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);
