To call swf external, xml does not appear

I am with a problem, I have my main file that has the normal menu that he would be principal.swf, I is using this to call the other .swf that he would be noticias.swf, that would have a project of the news in xml.


 // AS do button menu 2 chamar noticias.swf.
 menu2_mc.onPress = function ()
 {
 loadMovie("noticias.swf", 1);
 };
 

what I am using in xml is this


 // noticias xml
 stop ();
 //
 System.useCodepage=true
 //call xml e css
 var estilo = new TextField.StyleSheet ();
 var arquivo_css = "xml/jr.css";
 estilo.load (arquivo_css);
 estilo.onLoad = function (correto)
 {
 if (correto)
 {
  var meuXML:XML = new XML ();
  meuXML.ignoreWhite=true
  meuXML.load ("xml/jr.xml");
  meuXML.onLoad = function ()
  {
   _root.tela_mc.plana_mc.jr_txt.text = meuXML;
  };
 }
 jr_txt.styleSheet = estilo;
 };
 

my problem is following, when I compels my file noticias.swf it appears normal with the news, but when I am in the file principal.swf and click in button 2 menu it brings me the file noticias.swf but without xml, xml does not appear no way, somebody knows as I can fixed this?
