刚开始学XMLHTTP，试写的一个读取XML的JS脚本，没什么技术含量，主要用来读取一个类似于通讯录的XML文件。

------------------------------js-----------------------------------
<script type="text/javascript">
var xmlHttp;

//创建对象
function createXMLHttpRequest(){
 if (window.ActiveXObject){
  xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
 }else if (window.XMLHttpRequest){
  xmlHttp = new XMLHttpRequest("Msxml2.XMLHTTP.3.0");
 }
}

//发请请求
function doSearch(url){
 createXMLHttpRequest();
 xmlHttp.onreadystatechange = handleStateChange;
 xmlHttp.open("GET",url,"true");
 xmlHttp.send(null);
}

//处理响应
function handleStateChange(){
 if (xmlHttp.readyState == 4){
  if (xmlHttp.status == 200){
   parseResults();
  }
 }
}

//取得URL
function createURL(text){
 var url;
 url = "BranchAreaInfo.asp?AreaID=";
 if (text != ""){
  url += escape(text);
  doSearch(url);
 }
}

//读取XML文件
function parseResults(){

 var results = xmlHttp.responseXML;
 var sDiv = "";

 var shop = "null";
 var name ="";
 var address = "";
 var phone = "";
 var fax = "";

 var hhitshop = results.getElementsByTagName("shop");
 for (var i = 0; i< hhitshop.length; i++){
  shop =  hhitshop[i];
  name = shop.getElementsByTagName("name")[0].firstChild.nodeValue;
  phone = shop.getElementsByTagName("phone")[0].firstChild.nodeValue;
  fax = shop.getElementsByTagName("fax")[0].firstChild.nodeValue;
  address = shop.getElementsByTagName("address")[0].firstChild.nodeValue;

  sDiv += addDiv(name,photo,address,phone,fax);
 }
 document.getElementById("results").innerHTML = sDiv;
}

//输出格式化
function addDiv(name,photo,address,phone,fax){
 var WDiv = "<div class='shop_list'>";
 WDiv += "<a href='#'><img alt='"+ name +"' src='"+ photo +"' /></a>";
 WDiv += "<dl>";
 WDiv += "<dt><a href='#'>名称</a></dt>";
 WDiv += "<dd>电话："+ phone +"</dd>";
 WDiv += "<dd>传真："+ fax +"</dd>";
 WDiv += "<dd>地址："+ address +"</dd>";
 WDiv += "</dl>";
 WDiv += "</div>";
 
 return WDiv;
}
</script>
