My MovieClipLoader doesnt work in for loop. need help

1

i want preloaders for my external jpgs but also need to load them one by one, not random. i found some samples but they are more complex. i just want to do it with very simple way. there is an example http://www.ovalpartnership.com/main.php?lang=eng .

this is my code.


x_space = 0;
function loadXML(loaded) {
    if (loaded) {
        xmlNode = this.firstChild;
        total = xmlNode.childNodes.length;
        for (i=0; i<total; i++) {
            id = xmlNode.childNodes*.attributes.id;
            holder.attachMovie("intro_imgs","image"+i,i,{_x:x_space, _y:0});

            var mcLoader:MovieClipLoader = new MovieClipLoader();
            var listener:Object = new Object();
            mcLoader.addListener(listener);
            mcLoader.loadClip("prj_imgs/"+id+"_1.jpg",holder["image"+i].img_holder);


            listener.onLoadStart = function(target_mc:MovieClip) {
                holder["image"+i].bar._xscale = 0;
            };

            listener.onLoadProgress = function(target_mc:MovieClip, bytesLoaded:Number, bytesTotal:Number) {
                holder["image"+i].bar._xscale = Math.round(bytesLoaded/bytesTotal*100);
            };

            listener.onLoadComplete = function(target_mc:MovieClip) {
                holder["image"+i].bar.removeMovieClip();
            };

            x_space = x_space+300;
        }
    } else {
        content = "file not loaded!";
    }
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("projects.xml");
