$.get() isn't synchronous, the "return" will occur before the request
has finished.
You could give this a try, instead:
function LerXML(ordem) {
var diretorio;
$.ajax({
type: "GET",
url: "../modulos.xml",
async: false,
success: function(xmldataset){
diretorio = $("diretorio:eq(" + ordem + ")" , xmldataset);
}
});
return diretorio.text();
}
alert(LerXML(0));

Of course, synchronous XML requests can slow down your application -
so it would, most likely, be preferred to write your code using a
callback, instead.
