public class Dom4jtest {

Create a document instance using the Documenthelper class. Documenthelper is the dom4j API factory class that generates XML document nodes
Document doc = Documenthelper.createdocument ();

Use the AddElement () method to create the root element catalog. AddElement () is used to add elements to an XML document
Element address = doc.addelement ("Address");

Add a processing instruction using the Addprocessinginstruction () method in the element
Address.addprocessinginstruction ("Target", "text");

Element listelement = address.addelement ("HFHWFW");

Element countryelement = listelement.addelement ("Country");
To add a property to a country element using the AddAttribute () method
Countryelement.addattribute ("Country", "the");

Element cityelement = listelement.addelement ("city");
Use the SetText () method to set the text of the city element
Cityelement.settext ("Tongcheng");

Element codeElement = listelement.addelement ("code");
Add a comment using the AddComment () method
Codeelement.addcomment ("This is post code!");
Codeelement.settext ("231430");

try {
XMLWriter XMLWriter = new XMLWriter (New FileWriter ("D:/aaaa.xml"));
Xmlwriter.write (DOC);
Xmlwriter.close ();
catch (IOException e) {
E.printstacktrace ();
}
}
}

Run the generated XML file as follows (Csdn is not familiar with the layout of the document, make it look!): <?xml version= "1.0" encoding= "UTF-8"?> -< address > <?target text?> - < HFHWFW > < Country country = " " "/> ; City > tongcheng </City > - < code > - <!--this is post code! --> 231430 </code >
