DOM生成XML文档 
 import java.io.File;

 import javax.xml.parsers.DocumentBuilder;

 import javax.xml.parsers.DocumentBuilderFactory;

 import javax.xml.transform.OutputKeys;

 import javax.xml.transform.Transformer;

 import javax.xml.transform.TransformerFactory;

 import javax.xml.transform.dom.DOMSource;

 import javax.xml.transform.stream.StreamResult;

 import org.w3c.dom.Document;

 import org.w3c.dom.Element;

 public class DOM_Create_XML {

     public static void main(String[] args) throws Exception {

         DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

         DocumentBuilder builder = factory.newDocumentBuilder();

         Document doc = builder.newDocument();

         Element addresslist = doc.createElement("addresslist");

         Element linkman = doc.createElement("linkman");

         Element name = doc.createElement("name");

         Element email = doc.createElement("email");

         name.appendChild(doc.createTextNode("李兴华"));

         email.appendChild(doc.createTextNode("lxh@163.com"));

         linkman.appendChild(name);

         linkman.appendChild(email);

         addresslist.appendChild(linkman);

         doc.appendChild(addresslist);

         TransformerFactory tf = TransformerFactory.newInstance();

         Transformer transformer = tf.newTransformer();

         transformer.setOutputProperty(OutputKeys.ENCODING, "GBK");

         DOMSource domSource = new DOMSource(doc);

         StreamResult result = new StreamResult(new File("D:")+File.separator+"output.xml");

         transformer.transform(domSource, result);

     }

 }

运行程序，D盘下生成一个output.xml文档：

<?xml version="1.0" encoding="GBK" standalone="no"?><addresslist><linkman><name>李兴华</name><email>lxh@163.com</email></linkman></addresslist>

整理一下格式：

 <?xml version="1.0" encoding="GBK" standalone="no"?>

 <addresslist>

     <linkman>

         <name>李兴华</name>

         <email>lxh@163.com</email>

     </linkman>

 </addresslist>
