请教:怎样用DOM解析xml文件

我前几天也在做这个列子，原理一样。<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<script type="text/javascript">
function readXml(){
    //创建一个xml节点
    var xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
    xmlDoc.async=false;//设置异步调用
    xmlDoc.load("NewFile.xml");  //加载xmlwenj
    var items=xmlDoc.selectNodes("/camList/item");  //读取节点，相等于根结点
    var arr = [];
    //循环读取，把属性保存在一个对象里，然后把对象放入数组
    for(var i=0;i<items.length;i++)
    {
        var obj={};
        obj.camId = items(i).childNodes(0).text;  //第一个节点
        obj.camName = items(i).childNodes(1).text;
        arr.push(obj);    
    }
    var oSelect1=document.getElementById("showCamera1"); //获取网页里的下拉框对象
    var oSelect2=document.getElementById("showCamera2");
    var oSelect3=document.getElementById("showCamera3");
    var oSelect4=document.getElementById("showCamera4");
    //排序
    var newArr = arr.sort(function(x,y){return x.order>y.order?1:-1;});
    for(var i=0;i<newArr.length;i++)
    {
        //document.write("order:"+newArr[i].camId+" title:" + newArr[i].camName +"<br />");
        var oOption=document.createElement("OPTION"); 
        oSelect1.options.add(oOption);
        oOption.innerText=newArr[i].camName;
        oOption.value=newArr[i].camId;
        oSelect2.options.add(new Option(newArr[i].camName,newArr[i].camId));
        oSelect3.options.add(new Option(newArr[i].camName,newArr[i].camId));
        oSelect4.options.add(new Option(newArr[i].camName,newArr[i].camId));
    }
}
function save(){
        var oSelect1=document.getElementById("showCamera1"); //获取网页里的下拉框对象
    var oSelect2=document.getElementById("showCamera2");
    var oSelect3=document.getElementById("showCamera3");
    var oSelect4=document.getElementById("showCamera4");
        var tempksrq=oSelect1.options[oSelect1.selectedIndex].value;
        var texts=oSelect1.options[oSelect1.selectedIndex].text;
        alert(tempksrq);
        alert(texts);
    }
