Fix jQuery plugin xslt.js not working in Firefox 3.x

First of all, thanks Johann for his excellent jQuery XSLT plugin here.

Unfortunately, this one doesn't work with jQuery 1.5 in Firefox 3. One of the reasons is the readyState was changed to 0 after $.ajax loaded the xml and xslt files. Below is my fix by replacing line 84-118 in jquery.xslt.js with the following:
var change = function() {
    if (xm.readyState == xs.readyState && !transformed) {
        var processor = new XSLTProcessor();
        if ($.isFunction(processor.transformDocument)) {
            // obsolete Mozilla interface
            resultDoc = document.implementation.createDocument("", "", null);
            processor.transformDocument(xm.responseXML, xs.responseXML, resultDoc, null);
            target.html(new XMLSerializer().serializeToString(resultDoc));
        else {
            resultDoc = processor.transformToFragment(xm.responseXML, document);
        transformed = true;

if (str.test(xml)) {
    xm.responseXML = new DOMParser().parseFromString(xml, "text/xml");
else {
    xm = $.ajax({ dataType: "xml", url: xml});

if (str.test(xslt)) {
    xs.responseXML = new DOMParser().parseFromString(xslt, "text/xml");
else {
    xs = $.ajax({ dataType: "xml", url: xslt});
return this;
Will contact the author and update the post later...
(Update: the author hasn't responded, but I created a better solution here.)

jQuery "Object Expected" error in IE

I encountered this problem when prototyping some SharePoint webparts. It actually works well in Firefox and Chrome. Here's the snippet for illustration:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<script type="text/javascript" src="../js/jquery-1.5.min.js"></script>

<script type="text/javascript">

    $(function() { // <=> $(document).ready(function() {
By adding one line of code in line 7 before $(function(),
alert(typeof $);
it prompts "undefined", meaning jQuery is not loaded by IE. The solution is quite simple, IE->Tools->Internet Options->Security, by default it is High, either change it to Medium, or use custom level then enable Scripting->Active scripting (IE8). Now it alerts "function" and jQuery is working nifty then.
