Q: How to manipulate the nodes and attributes of an XML document using the XmlDocument type

Some of the test code is posted below:

classProgram {Static voidMain (string[] args) {            stringXmlpath ="Test.xml"; XmlDocument XML=NewXmlDocument (); Xml.            Load (Xmlpath); Console.WriteLine ("the original XML document is:");            Printxmldocument (XML); Console.WriteLine ("After you create a new node:");            AddNode (XML);            Printxmldocument (XML); Console.WriteLine ("after editing the node:");            Editnode (XML);            Printxmldocument (XML);        Console.ReadLine (); }        Static voidprintxmldocument (XmlDocument XML) {XML.            Save (Console.Out);        Console.WriteLine (); }        Static voidAddNode (XmlDocument xml) {XmlNode NewNode= XML. CreateElement (" Book"); XmlAttribute Newattribute= XML. CreateAttribute ("name"); Newattribute.value="BOOK3";            NewNode.Attributes.Append (Newattribute); XmlNode Auth= XML. CreateElement ("Auth"); Auth. InnerText="Z3"; XmlNode Date= XML. CreateElement ("Date"); Date. InnerText="2011-10-1";            Newnode.appendchild (auth);            Newnode.appendchild (date); Xml.        Documentelement.appendchild (NewNode); }        Static voideditnode (XmlDocument xml) {XmlNode node=XML.            DocumentElement; XmlNode Editnode= node. Childnodes[node. Childnodes.count-1]; editnode.attributes["name"]. Value ="Book4"; Editnode.selectsinglenode ("Auth"). InnerText ="Z4"; Editnode.selectsinglenode ("Date"). InnerText ="2012-09-18"; }        Static voiddeletenode (XmlDocument xml) {XmlNode node=XML.            DocumentElement; XmlNode RemoveNode= node. Childnodes[node. Childnodes.count-1]; RemoveNode.Attributes.RemoveAt (0); Node.        RemoveChild (RemoveNode); }    }
