Import Org.dom4j.DocumentHelper;

Import org.dom4j.Element; /** * @author WSJ * * * public class Test1 {public static void main (string[] args) throws Exception {Document DOM=DOCU Menthelper.createdocument ()//create XML file Element root=dom.addelement ("Xval");//Add root element, Xval root.addattribute ("X", "
  The value of the X string ");
  Root.settext ("Middle value of xval label");
  String Xml=dom.asxml ();
  SYSTEM.OUT.PRINTLN (XML);
  File F=new file ("D:/xml.xml");
  PrintWriter pw=new PrintWriter (f);

  //Add Property child nodes in//addtext node, add attribute Name value to "username"
  Classelement.addelement ("Property"). AddAttribute ("name", "username");
  Format output file
  OutputFormat format=outputformat.createprettyprint ();
  Declare the file
  XMLWriter writer=new XMLWriter (New FileWriter ("User2.xml"), format);
  Write out document
