    if (xmlHttp.status == 200 || xmlHttp.status == 0){
    // 取得XML的DOM对象
    var xmlDOM = xmlHttp.responseXML;
    // 取得XML文档的根
    var root = xmlDOM.documentElement;
    try
    {
    // 取得<info>结果
    var info = root.getElementsByTagName('info');
    // 显示返回结果
    alert("responseXML's value: " + info[0].firstChild.data);
