用JS读取XML的例子

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>

<?xml version="1.0" encoding="utf-8" ?>
<hhitshop>

<shop>
