function loadXMLDoc(url){
  var xmlhttp;
  var txt,x,xx,i;
  if(window.XMLHttpRequest){
    // code for IE7+, Firefox, Chrome, Opera, Safari
    xmlhttp=new XMLHttpRequest();
  }
  else{
    // code for IE6, IE5
    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
  xmlhttp.onreadystatechange=function(){
    if (xmlhttp.readyState==4 && xmlhttp.status==200){
      txt="<table border='1'><tr><th>Title</th><th>Artist</th></tr>";
      x=xmlhttp.responseXML.documentElement.getElementsByTagName("cd");
      for (i=0;i<x.length;i++){
        txt=txt + "<tr>";
        xx=x[i].getElementsByTagName("title");
        {
          try{
            txt=txt + "<td>" + xx[0].firstChild.nodeValue + "</td>";
          }
          catch (er){
            txt=txt + "<td> </td>";
          }
        }
        xx = x[i].getElementsByTagName("artist");
        {
          try{
            txt=txt + "<td>" + xx[0].firstChild.nodeValue + "</td>";
          }
          catch (er){
            txt=txt + "<td> </td>";
          }
        }
        txt=txt + "</tr>";
      }
      txt=txt + "</table>";
      document.getElementById('txtCDInfo').innerHTML=txt;
    }
  }
  xmlhttp.open("GET",url,true);
  xmlhttp.send();
}
window.onload=function(){
  var obt=document.getElementById("bt");
  obt.onclick=function(){
    loadXMLDoc('demo/ajax/xml/antzone.xml')
  }
}
</script>
</head>
<body>
<div id="txtCDInfo"></div>
<input type="button" id="bt" value="檢視效果"/>
</body>
</html>

上面的程式碼點選按鈕可以實現載入解析效果，xml檔案內容程式碼如下:
