XML not showing load progress...

Question

I have a fla file that loads a slide show from an XML file. The xml file contains info about each slide. There's over a 100 slides so the loading takes some time. However I'm not getting actual load progress. It traces nothing until after the load is complete and then it shows the progress that it should have traced one by one, however it traced them all at once on the complete. Because it's not firing the onProgress correctly my preloader is rendered useless. Am I doing something wrong on is this a bug in Flash?
//======================================================================================== =================================================
//     load xml
//======================================================================================== =================================================
var xmlLoader:URLLoader = new URLLoader();
var xmlData:XML = new XML();
xmlLoader.addEventListener(Event.COMPLETE, LoadXML);
xmlLoader.addEventListener(ProgressEvent.PROGRESS, LoadingXML);
function LoadXML(e:Event):void {
trace("complete");
xmlData = new XML(e.target.data);
ParseSlides(xmlData);
xmlLoader.removeEventListener( ProgressEvent.PROGRESS, LoadXML);
xmlLoader.removeEventListener( Event.COMPLETE, LoadingXML);
MovieClip(root).loading_mc.x = 1500;
MovieClip(root).loading_mc.bar.width = 1;
MovieClip(root).loading_mc.loading_txt.text = "";
function LoadingXML(e:ProgressEvent):void {
//trace("Loading..." + Math.ceil(e.bytesLoaded * 100 / e.bytesTotal) + "%");
var loaded:Number = e.target.bytesLoaded;
var total:Number = e.target.bytesTotal;
var pct:Number = loaded / total;
trace(pct);
MovieClip(root).loading_mc.x = 500;
MovieClip(root).loading_mc.bar.width = pct * 194;
MovieClip(root).loading_mc.loading_txt.text = "Loading XML... " + (Math.round(pct * 100)) + "%";
xmlLoader.load(new URLRequest("XML/SectionII.xml"));
HERE IS THE OUTPUT: All at once when the complete fires

Actually it still doesn't work like I need it to. The loading of the xml preloader only works if the temporary internet files are gone. Which means that the time I need the loader is during the parsing of the xml process. I have a function that creates an object for each slide after the xml loads. It runs through a for loop, however the loader won't appear and work during the for loop. It only works after its finished.
function ParseSlides(slideInput:XML):void {
// create a list of slide items
var slideList:XMLList = slideInput.Slide;
var slideSize:Number = slideList.length();
var buildPct:Number;
// run through list to build each slide object
for (var i:Number = 0; i < slideList.length(); i++) {
  // get progress of building slides
  buildPct = Math.ceil(i / slideSize);
  MovieClip(root).loading_mc.bar.width = buildPct * loadBarWidth;
  MovieClip(root).loading_mc.loading_txt.text = "Building Slides... " + (Math.round(buildPct * 100)) + "%";
  // build slide id and name
  var idElement:XML = slideInput.Slide.attribute("ID")[i];
  var headerElement:XML = slideInput.Slide.header.copy[i];
  var headerAnimationElement:XML = slideInput.Slide.header.animation[i];
  var headerStartXElement:XML = slideInput.Slide.header.startx[i];
  var headerStartYElement:XML = slideInput.Slide.header.starty[i];
  var headerFinishXElement:XML = slideInput.Slide.header.finishx[i];
  var headerFinishYElement:XML = slideInput.Slide.header.finishy[i];
  var headerStartAlphaElement:XML = slideInput.Slide.header.startAlpha[i];
  var headerFinishAlphaElement:XML = slideInput.Slide.header.finishAlpha[i];
  var headerDelayElement:XML = slideInput.Slide.header.delay[i];
  var headerSecondsElement:XML = slideInput.Slide.header.seconds[i];
  var subheaderElement:XML = slideInput.Slide.subheader.copy[i];
  var subheaderAnimationElement:XML = slideInput.Slide.subheader.animation[i];
  var subheaderStartXElement:XML = slideInput.Slide.subheader.startx[i];
  var subheaderStartYElement:XML = slideInput.Slide.subheader.starty[i];
  var subheaderFinishXElement:XML = slideInput.Slide.subheader.finishx[i];
  var subheaderFinishYElement:XML = slideInput.Slide.subheader.finishy[i];
  var subheaderStartAlphaElement:XML = slideInput.Slide.subheader.startAlpha[i];
  var subheaderFinishAlphaElement:XML = slideInput.Slide.subheader.finishAlpha[i];
  var subheaderDelayElement:XML = slideInput.Slide.subheader.delay[i];
  var subheaderSecondsElement:XML = slideInput.Slide.subheader.seconds[i];
  var audioElement:XML = slideInput.Slide.audio[i];
  var videoElement:XML = slideInput.Slide.video[i];
  // create new slide object
  slide[idElement] = new Object();
  slide[idElement].name = idElement;
  // set header information
  slide[idElement].header = headerElement;
  slide[idElement].headerAnimation = headerAnimationElement;
  slide[idElement].headerStartX = headerStartXElement;
  slide[idElement].headerStartY = headerStartYElement;
  slide[idElement].headerFinishX = headerFinishXElement;
  slide[idElement].headerFinishY = headerFinishYElement;
  slide[idElement].headerStartAlpha = headerStartAlphaElement;
  slide[idElement].headerFinishAlpha = headerFinishAlphaElement;
  slide[idElement].headerDelay = headerDelayElement;
  slide[idElement].headerSeconds = headerSecondsElement;
  slide[idElement].subheader = subheaderElement;
  slide[idElement].subheaderAnimation = subheaderAnimationElement;
  slide[idElement].subheaderStartX = subheaderStartXElement;
  slide[idElement].subheaderStartY = subheaderStartYElement;
  slide[idElement].subheaderFinishX = subheaderFinishXElement;
  slide[idElement].subheaderFinishY = subheaderFinishYElement;
  slide[idElement].subheaderStartAlpha = subheaderStartAlphaElement;
  slide[idElement].subheaderFinishAlpha = subheaderFinishAlphaElement;
  slide[idElement].subheaderDelay = subheaderDelayElement;
  slide[idElement].subheaderSeconds = subheaderSecondsElement;
  // set the audio in the slide
  slide[idElement].audio = audioElement;
  // set the video in the slide
  slide[idElement].video = videoElement;
  // push new slide to the array of slide names
  slidesArray.push(slide[idElement].name);
//MovieClip(root).loading_mc.x = 1500;
//MovieClip(root).loading_mc.bar.width = 1;
//MovieClip(root).loading_mc.loading_txt.text = "";
// start slide
buildSlide();
