Problema lettura XML con Javascript da FIREFOX

[bluego78]

HO PROVATO COSI' MA NON VA...

function leggiNodi(indice, xml) 
{
	//if(navigator.userAgent.indexOf("Gecko")!=(-1)){
	if (window.ActiveXObject){
			alert ("stai usando internet explorer")
			var xmldoc = new ActiveXObject("Msxml2.DOMDocument.3.0");
			xmldoc.async = "false";
			var languageFolder = getCookie('eltracLanguage');
			xmldoc.load("text/"+languageFolder+"/"+xml+"");	
			xmldoc.childNodes[1].childNodes[indice].childNodes[0].text
			var valoreNodo = xmldoc.childNodes[1].childNodes[indice].childNodes[0].text;
			document.write (valoreNodo);
	}else{
			alert ("non stai usando internet explorer");
			var languageFolder = getCookie('eltracLanguage');
			var xmldoc = new XMLHttpRequest();
			xmldoc.open("GET","text/"+languageFolder+"/"+xml+"", false);
			xmldoc.send(null);
			myXML = xmldoc.responseXML;
			myXML.childNodes[1].childNodes[indice].childNodes[0].text
			var valoreNodo = myXML.childNodes[1].childNodes[indice].childNodes[0].text;
			document.write (valoreNodo);
	}
}
