How to Reload XML file in ActionScript?

Question

Hi,
I have a problem with action script.
How can I reload/update xml file per 5 minutes in actionscript?
isn't there someway i can do to complete the script?
my script:
====================================
delay = 3000;
function loadXML(loaded) {
     if (loaded) {
          xmlNode = this.firstChild;
          schedule = [];
          remark = [];
          term = [];
          total = xmlNode.childNodes.length;
          for (i=0; i<total; i++) {
               schedule[i] = xmlNode.childNodes[i].childNodes[4].firstChild.nodeValue;
               remark[i] = xmlNode.childNodes[i].childNodes[6].firstChild.nodeValue;
               term[i] = xmlNode.childNodes[i].childNodes[7].firstChild.nodeValue;
          firstData();
     } else {
          content = "file not loaded!";
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("mydata.xml");
p = 0;
function nextData() {
     if (p<(total-1)) {
          p++;         
          schedule_txt.text = schedule[p];
          remark_txt.text = remark[p];
          term_txt.text = term[p];
          slideshow();
function firstData() {
     schedule_txt.text = schedule[p];
     remark_txt.text = remark[p];
     term_txt.text = term[p];
     slideshow();
function slideshow() {
     myInterval = setInterval(pause_slideshow, delay);
     function pause_slideshow() {
          clearInterval(myInterval);
          if (p == (total-1)) {
               p = 0;
               firstData();
          } else {
               nextData();
===================================

Take a similar approach with another setInterval and have your xmlData loading code be in the function that the interval calls.
