xml 生成

Document   dod =DocumentHelper.createDocument();   //建立xml 
     Element ele = dod.addElement("student");    
     Element tet = ele.addElement("yyy");
     Element nameElement = tet.addElement("name");
     nameElement.addText("sss");
     Element tets = ele.addElement("tets");
     tets.addText("sssdd");
    /* System.out.println(dod.asXML());*/ //生成  xml 字串
     try {
    Writer fileWriter = new FileWriter("c:\\module.xml"); 
                //dom4j提供了專門寫入檔案的物件XMLWriter
    XMLWriter xmlWriter = new XMLWriter(fileWriter); 
             xmlWriter.write(dod); 
             xmlWriter.flush(); 
             xmlWriter.close();
  } catch (IOException e) {
   e.printStackTrace();
  }

xml  解析

 SAXReader  reader  =new SAXReader();
  try {
   Document document = reader.read(new File("c:/module.xml"));
   Element Ele = document.getRootElement();
   System.out.println(Ele.getName());
   Element fooElement;
   for(Iterator i=Ele.elementIterator("yyy");i.hasNext();){
                 fooElement=(Element)i.next();
                 System.out.println("ss:"+fooElement.elementText("name"));
         } 
     } catch (DocumentException e) {
   e.printStackTrace();
  } 
 }
