-- Generate Parent Element
if(!File.Exist(Path))
{
XmlTextWriter writer = new XmlTextWriter(Path);
writer.Formatting = Formatting.Indented;
writer.WriteStartDocument();
writer.WriteStartElement("ElementName");
writer.WriteEndElement();
writer.WriteEndDocument();
writer.Close();
}
-- Generate Child Element
XmlDocument xmldoc = new XmlDocument();
XMLNode root = xmldoc.DocumentElement;
xmldoc.Load(path);
XmlElement ChildInfo = xmldoc.CreateElement("ChildElement");
ChildInfo.InnerText = "Test";
root.AppendChild(childInfo);
