怎么在后天获取xml的数据，并返回到前台页面

前台是一个导航菜单，需要获取xml中的名称属性，并放置在li里边，求大神解救

 PrintWriter writer = null;
        try{
            response.setContentType("text/xml;charset=UTF-8");
            writer = response.getWriter();
            writer.write(result);
            writer.flush();
        }catch(Exception e){
            e.printStackTrace();
        }

 public class XmlTOHServlet extends HttpServlet {  


    public void doPost(HttpServletRequest request, HttpServletResponse response)  
            throws ServletException, IOException {  
        request.setCharacterEncoding("UTF-8");  
        response.setContentType("text/html; charset=UTF-8");  

        StringBuffer bxml = new StringBuffer();  

        String line = null;  
       //从获得请求中的数据流  
        try {  
              BufferedReader reader = request.getReader();  
              while((line = reader.readLine()) != null) {  
                   bxml.append(line);  
              }  
         }  
         catch(Exception e) {  
              System.out.println(e.toString());  
         }  

         String xml =bxml.toString();  

         Document xmlDoc = null;  
         try {  

               xmlDoc = DocumentBuilderFactory.newInstance()  
               .newDocumentBuilder()  
               .parse(new ByteArrayInputStream(xml.getBytes()));  

         }  
         catch(ParserConfigurationException e) {  
              System.out.println(e.getStackTrace());  
         }  
         catch(SAXException e) {  
              System.out.println( e);  
         }  


        String uname = xmlDoc.getElementsByTagName("name").item(0).getFirstChild().getNodeValue();  
        String city = xmlDoc.getElementsByTagName("ad").item(0).getFirstChild().getNodeValue();  
        String street =  xmlDoc.getElementsByTagName("yb").item(0).getFirstChild().getNodeValue();  

        String responseText = "您发送给"+uname+"地址是"+city+"邮编是"+street+"邮件，还需要一天到达目的地！";  

        response.setContentType("text/xml; charset=UTF-8");  
        response.setHeader("Cache-Control", "no-cache");  
        PrintWriter out = response.getWriter();  
        out.println(responseText);  

        out.close();  
    }  

}
