下面利用异步对象获取该XML，并将所有的项都罗列在表格中，初始化对象的方法与获取文本完全相同，代码如下：

    var xmlHttp;

            function createXMLHttpRequest() {
                if (window.ActiveXObject)
                    xmlHttp = new ActiveXObject("Mincrosoft,XMLHttp");
                else if (window.XMLHttpRequest)
                    xmlHttp = new XMLHttpRequest();
            }

当用户单击按钮时发生异步请求，并获取responseXML对象，代码如下

    function getXML(addressXML) {
                var sUrl = addressXML + "?timestamp=" + new Date();
                createXMLHttpRequest();
