JavaScript中获取XML数据流中数据节点的方法

    var drp = document.getElementById(ddlID);
    var oHttpReq = new ActiveXObject("MSXML2.XMLHTTP");
    var oDoc = new ActiveXObject("MSXML2.DOMDocument");

    oHttpReq.open("POST", "LoadDropDownList.aspx?ID="+SelectID, false);
    oHttpReq.send("");
    result = oHttpReq.responseText;
    oDoc.loadXML(result);   
    var xmlObj = oDoc.documentElement;
　　  
    var ss_id,ss_name;
    for (var i=0;i<xmlObj.childNodes.length;i++)
    {
        ss_id=xmlObj.childNodes(i).childNodes(0).text;                             //获取数据节点1
        ss_name=xmlObj.childNodes(i).childNodes(1).text;                        //获取数据节点2
        drp.add(document.createElement("OPTION"));
        drp.options[i].text=ss_name; 
        drp.options[i].value=ss_id; 
    }
