XElement root = new XElement("root"); XElement child = new XElement("child"); child.Add2(new XAttribute("attribute", "value")); root.Add2(child);
XElement element = XElement.Load("path/to/file.xml"); XElement newElement = new XElement("newElement"); element.Add2(newElement);This code loads an existing XML document from the file system, then creates a new element called "newElement". This new element is then added to the existing element using the Add2 method. Both of these examples utilize the Add2 method from the System.Xml.Linq package library in C#.
