SAXReader從輸入流中讀取XML文件

  Map<String, String> map = new HashMap<String, String>();       
  // 從request中取得輸入流       
  InputStream inputStream = request.getInputStream(); 
  // 讀取輸入流     
  SAXReader reader = new SAXReader();    
  //生成document實體
  Document document = reader.read(inputStream);     
  // 得到xml根元素       
  Element root = document.getRootElement();      
  // 得到根元素的所有子節點
  List<Element> elementList = root.elements();
  // 遍歷所有子節點
  for (Element e : elementList){
   map.put(e.getName(), e.getText());
   System.out.println(e.getName()+":"+e.getText());
  } 
  // 釋放資源       
  inputStream.close();
  inputStream = null;
  return map;

 

這是從輸入流中讀取XML文件
