输出xml

输出xml

在struts2.Xml中写：
<? xml version = " 1.0 "  encoding = " UTF-8 " ?>
  <! DOCTYPE struts PUBLIC
     " -//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN "
     " http://struts.apache.org/dtds/struts-2.1.7.dtd " >
     < struts >
         < package  name = " myxml "    extends = " struts-default " >
         <!--  输出xml的方法不写result  -->
             < action name = " xml "   class = " com.yjw.web.MyxmlAction " ></ action >
         </ package >
     </ struts >
在action中写：
package  com.yjw.web;

import  java.io.PrintWriter;

import  javax.servlet.http.HttpServletResponse;

import  org.apache.struts2.ServletActionContext;

import  com.opensymphony.xwork2.Action;

public   class  MyxmlAction  implements   Action {

    public String execute() throws Exception {
        HttpServletResponse  response = ServletActionContext.getResponse();
        response.setContentType("text/xml;charset=UTF-8");
        PrintWriter  out = response.getWriter();
        out.print("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
        out.print("<root>");
        for(int i=0;i<5;i++){
            out.print("<person>");
            out.print("<name>person"+i+"</name>");
            out.print("</person>");
        }
        out.print("</root>");
        //一定要返回null
        return null;
    }

}
在jsp里写：
< body >
   < input  type = " button "   value = " xml "   id = " btnxml " />
   < div  id = " mydiv " ></ div >
   < script type = " text/javascript "   src = js / jquery - 1.5 . 1 .min.js ></ script >
   < script  type = " text/javascript " >
              $(document).ready(function() {
                  $("#btnxml").click(function(){
                      $.get("xml.action",function(xml){
                          $(xml).find("person").each(function(){
                              var name = $(this).find("name").text();
                              $("#mydiv").html($("#mydiv").html()+name+'<br/>');
                          });
                      });
                      
                  });
              } );
   </ script >
   </ body >
