JS 解析Xml

loadXML = function (xmlString) {
    var xmlDoc = null;
    //判断浏览器的类型
    //支持IE浏览器
    if (!window.DOMParser && window.ActiveXObject) {   //window.DOMParser 判断是否是非ie浏览器
        var xmlDomVersions = ['MSXML.2.DOMDocument.6.0', 'MSXML.2.DOMDocument.3.0', 'Microsoft.XMLDOM'];
        for (var i = 0; i < xmlDomVersions.length; i++) {
            try {
                xmlDoc = new ActiveXObject(xmlDomVersions[i]);
                xmlDoc.async = false;
                xmlDoc.loadXML(xmlString); //loadXML方法载入xml字符串
                break;
            } catch (e) {
            }
        }
    }
        //支持Mozilla浏览器
    else if (window.DOMParser && document.implementation && document.implementation.createDocument) {
        try {
            /* DOMParser 对象解析 XML 文本并返回一个 XML Document 对象。

            * parseFromString(text, contentType) 参数text:要解析的 XML 标记 参数contentType文本的内容类型

            domParser = new DOMParser();
            xmlDoc = domParser.parseFromString(xmlString, 'text/xml');
        } catch (e) {
        }
    }

调用方式：

var strDataXml = loadXML(sRtn);

var rooms = strDataXml.getElementsByTagName("Room");
for (i = 0; i < rooms.length; i++) {
    var arrRoom = new Array
    arrRoom[0] = rooms[i].getElementsByTagName("RoomGUID")[0].text;
    arrRoom[1] = rooms[i].getElementsByTagName("RoomInfo")[0].text;
    arrRoom[2] = rooms[i].getElementsByTagName("CstName")[0].text;
    arrRoom[3] = rooms[i].getElementsByTagName("BldArea")[0].text;
    arrRoom[4] = rooms[i].getElementsByTagName("TnArea")[0].text;
    arrRoom[5] = rooms[i].getElementsByTagName("AreaStatus")[0].text;
    arrRoom[6] = rooms[i].getElementsByTagName("BldCjPrice")[0].text;
    arrRoom[7] = rooms[i].getElementsByTagName("TnCjPrice")[0].text;
    arrRoom[8] = rooms[i].getElementsByTagName("RmbHtTotal")[0].text;
    arrRoom[9] = rooms[i].getElementsByTagName("QSDate")[0].text;
    arrRoom[10] = rooms[i].getElementsByTagName("alterType")[0].text;
    arrRoom[11] = rooms[i].getElementsByTagName("alterDate")[0].text;

    arrRoom[12] = rooms[i].getElementsByTagName("TradeGUID")[0].text;
    arrRoom[13] = rooms[i].getElementsByTagName("ContractGUID")[0].text;

    AddRoomToList(arrRoom)
}
