XML文件生成——借助JDOM

 import java.io.* ;
 import org.jdom.* ;
 import org.jdom.output.* ;
 public class DOMDemo {
     public static void main(String args[]) throws Exception {
         Element addresslist = new Element("addresslist") ;
         Element linkman = new Element("linkman") ;
         Element name = new Element("name") ;
         Element email = new Element("email") ;
         Attribute id = new Attribute("id","lxh") ;
         Document doc = new Document(addresslist) ;    // 定义Document对象
         name.setText("李兴华") ;
         name.setAttribute(id) ;    // 将属性设置到元素之中
         email.setText("[e-mail]") ;
         linkman.addContent(name) ;    // 设置关系
         linkman.addContent(email) ;
         addresslist.addContent(linkman) ;
         XMLOutputter out = new XMLOutputter() ;
         out.setFormat(out.getFormat().setEncoding("GBK")) ;    // 表示的是设置编码
         out.output(doc,new FileOutputStream(new File("D:" + File.separator + "address.xml"))) ;
     }
 }

要求在工程中引入jdom.jar
