Now its working on latest browser.
I have written the following code to solve the zxml.js issues. Hope it will help.

Code:
var zXml = {
    useActiveX: (window.ActiveXObject || "ActiveXObject" in window),
    useDom: document.implementation && document.implementation.createDocument && !(window.ActiveXObject || "ActiveXObject" in window),
    useXmlHttp: (typeof XMLHttpRequest != "undefined") && !(window.ActiveXObject || "ActiveXObject" in window)
};

zXml.ARR_XMLHTTP_VERS = ["MSXML2.XmlHttp.6.0", "MSXML2.XmlHttp.3.0"];
zXml.ARR_DOM_VERS = ["MSXML2.DOMDocument.6.0", "MSXML2.DOMDocument.3.0", "Microsoft.XMLDOM"];

function zXmlHttp() { }

zXmlHttp.createRequest = function () {
    if (zXml.useXmlHttp) {
        return new XMLHttpRequest();
    } else if (zXml.useActiveX) {
        if (!zXml.XMLHTTP_VER) {
            for (var i = 0; i < zXml.ARR_XMLHTTP_VERS.length; i++) {
                try {
                    new ActiveXObject(zXml.ARR_XMLHTTP_VERS[i]);
                    zXml.XMLHTTP_VER = zXml.ARR_XMLHTTP_VERS[i];
                    break;
                } catch (oError) { ; }
            }
        }

        if (zXml.XMLHTTP_VER) {
            return new ActiveXObject(zXml.XMLHTTP_VER);
        } else {
            throw new Error("Could not create XML HTTP Request.");
        }
    } else {
        throw new Error("Your browser doesn't support an XML HTTP Request.");
    }
};

zXmlHttp.isSupported = function () {
    return zXml.useXmlHttp || zXml.useActiveX;
};

function zXmlDom() { }
zXmlDom.createDocument = function () {
    if (zXml.useDom) {
        var oXmlDom = document.implementation.createDocument("", "", null);
        oXmlDom.parseError = {

            }
        };
        oXmlDom.__initError__();
        oXmlDom.addEventListener("load", function () {
