这样，你应该能够让你在找什么

String xml = "<tickets type=\"array\"><ticket><ticket-id type=\"integer\">6</ticket-id><status><id type=\"integer\">1706729</id><name>Completed</name><colour>black</colour></status></ticket><ticket><ticket-id type=\"integer\">5</ticket-id><status><id type=\"integer\">1706929</id><name>New</name><colour>White</colour></status></ticket></tickets>"; 
      Log.e("xml parsing ", xml); 
      try { 
       DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance(); 
       domFactory.setNamespaceAware(true); 
       domFactory.setIgnoringComments(true); 
       domFactory.setIgnoringElementContentWhitespace(true); 
       domFactory.setCoalescing(true); 
       DocumentBuilder domBuilder = null; 
       Document document = null; 

       try { 
        domBuilder = domFactory.newDocumentBuilder(); 
       } 
       catch (ParserConfigurationException parserConfigurationException) { 
        Logger.log(Logger.LEVEL_ERROR, FrameworkHelper.class.getName(), "getDocumentRoot", "ParserConfigurationException caught while creating DocumentBuilder object, " + parserConfigurationException.getMessage()); 
       } 

       document = domBuilder.parse(new ByteArrayInputStream(xml.getBytes()));//try catch 
       NodeList ticketList = document.getElementsByTagName("ticket"); 
       for (int i = 0; i < ticketList.getLength(); i++) { 
        Element ticketNode = (Element) ticketList.item(i); 
        String tickets = ticketNode.getNodeValue(); 
        NodeList statusList = ticketNode.getElementsByTagName("status"); 
        for (int j = 0; j < statusList.getLength(); j++) { 
        Element statusNode = (Element) statusList.item(j); 
        String statuses = statusNode.getNodeValue(); 
        NodeList nameList = statusNode.getElementsByTagName("name"); 
        for (int k = 0; k < nameList.getLength(); k++) { 
         Element nameNode = (Element) nameList.item(k); 
         String names = nameNode.getChildNodes().item(0).getNodeValue(); 
         Toast.makeText(this, "name: " + names, 
          Toast.LENGTH_SHORT).show(); 
        } 
        } 
       } 
      } catch (SAXException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 

但是，如果层次不是重要的是要保持和你只是想单独处理的名字你可以直接调用getElementsByTagName（“name”）
