loadMovie XML problem ( _root, _parent or this ???)

I am having problems loading an xml file from an swf. I have a dynamic calendar that I am using. I am loading the calendar.swf inside my parent.swf using the ; loadMovie("calendar.swf", "loadstage"); I have worked out all issues except the xml file that the calendar.swf calls for is not loading. It works fine when the swf is published on its own.
I does not work when the swf is loaded in the parent.swf.

HELP ME, PLEASE !!!!! THANK YOU VERY MUCH!!!!


THE ACTION SCRIPT !!!

XMLData = new XML();
XMLData.load("cal.xml");
XMLData.onload = viewApp;
function viewApp () {
mainTag = new XML();
arrCal = new Array();
arrDate = new Array();
arrMsg = new Array();
mainTag = this.firstChild.nextSibling;
if (mainTag.nodeName.toLowerCase() == "diary") {
arrCal = mainTag.childNodes;
for (i=0; i<=arrCal.length; i++) {
if (arrCal .nodeName == "cal") {
if ((arrCal.attributes.yearID == myNewYear) and (arrCal .attributes.monthID == myNewMonth)) {
arrDate = arrCal.childNodes;
for (j=0; j<=arrDate.length; j++) {
