ajax 之 XMLHttpRequest返回responseXML类型

  

    服务端代码

<%
response.setContentType("text/xml");  //解析为XML档
response.setHeader("Cache-Control","no-cache");
//out.println("<?xml version='1.0' encoding='ISO-8859-1'?>"); 不能插入该条代码
out.println("<company>");
out.println("<date>");
out.println("<compname>compname</compname>");
out.println("<contname>contname</contname>");
out.println("<address>address</address>");
out.println("<city>city</city>");
out.println("<country>country</country>");
out.println("</date>");
out.println("<date>");
out.println("<compname>compname2</compname>");
out.println("<contname>contname2</contname>");
out.println("<address>address2</address>");
out.println("<city>city2</city>");
out.println("<country>country2</country>");
out.println("</date>");
out.println("</company>");
%>

    客户端读取服务端返回的XML数据：

  

var msg=XMLHttpReq.responseXML;
var catalogId=msg.getElementsByTagName("city")[0].firstChild.nodeValue;  //获取第一个data内的city数据
    
alert(catalogId);
alert(msg.getElementsByTagName("country")[1].childNodes[0].nodeValue);//获取第二个data内的country数据
