Creating httpRequest for parser an XML page for browser android

Hello,
First I must excuse me for my poor English
I have developed a controller device that use jscript to refresh some data in a explorer page
this is the controller link sa712w.dynalias.net

If you use a browser as Firefox, Chrome, IE etc, you can see that are some data refreshed in real time: The temperature and humidity, the time for the next commutation, and the system status. The data is collected from a XML page ( called Variables.xml ) and then I refresh div tags to show the data.
The problem is when use an standard explorer into Android device, this data isn't showed.

I think the problem is the httprequest object creation. I can be mistaken

As this is a controller device, it can not have internet access. It could be connected only to a Lan .

This is the code for parser the page XML.

the file is "func.js"

// these are the variables to refresh
var jsLectTemp;
var jsLectHum;
var jsEstEq1;
var jsEstEq2;
var jsColEstEq1;
var jsColEstEq1;
var jsEstTemp;
var jsEst220;
var jsEstSec;
var jsEstModo;
var jsEstDelaymed;
var jsProxConm;
var jsDivCr1;
var jsDivCr2;
// -----------------------------
var wPagina;
// ----------------------------

// they are the variables to object
var xmlhttp;
var xmlDoc;

function Read_XML_File(pagina)
{
wPagina=pagina;
try {//Test for Internet Explorer
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false; //We want a synchronous connection
xmlDoc.load("variables.xml"); //Load the XML file
}catch(err){ //If ActiveX isn't going to work we use a more codified standard
try {//Every browser but Internet Explorer
xhttp=new XMLHttpRequest();
xhttp.open("GET","variables.xml",false);
xhttp.send("");
xmlDoc=xhttp.responseXML;
}catch(err){ //If that doesn't work, we produce an error .
<!-- alert("Your explorer isn't compatible with IneControl"); -->
return;
}

}

// this is the parser
jsLectTemp = xmlDoc.getElementsByTagName("LectTemp")[0].childNodes[0].nodeValue;
jsLectHum = xmlDoc.getElementsByTagName("LectHum")[0].childNodes[0].nodeValue;
jsEstEq1 = xmlDoc.getElementsByTagName("EstEq1")[0].childNodes[0].nodeValue;
jsEstEq2 = xmlDoc.getElementsByTagName("EstEq2")[0].childNodes[0].nodeValue;
jsEstTemp = xmlDoc.getElementsByTagName("EstTemp")[0].childNodes[0].nodeValue;
jsEst220 = xmlDoc.getElementsByTagName("Est220")[0].childNodes[0].nodeValue;
jsEstSec = xmlDoc.getElementsByTagName("EstSec")[0].childNodes[0].nodeValue;
jsEstModo = xmlDoc.getElementsByTagName("EstModo")[0].childNodes[0].nodeValue;
jsEstDelayMed = xmlDoc.getElementsByTagName("EstDelayMed")[0].childNodes[0].nodeValue;
jsProxConm = xmlDoc.getElementsByTagName("ProxConm")[0].childNodes[0].nodeValue;
jsDivCr1 = xmlDoc.getElementsByTagName("DivCr1")[0].childNodes[0].nodeValue;
jsDivCr2 = xmlDoc.getElementsByTagName("DivCr2")[0].childNodes[0].nodeValue;

document.getElementById("idLectTemp").innerHTML=jsLectTemp;
document.getElementById("idLectHum").innerHTML=jsLectHum;
document.getElementById("idEstEq1").innerHTML=jsEstEq1;
document.getElementById("CeldaEq1").className=jsEstEq1;
document.getElementById("idEstEq2").innerHTML=jsEstEq2;
document.getElementById("CeldaEq2").className=jsEstEq2;
document.getElementById("idEstTemp").innerHTML=jsEstTemp;
document.getElementById("CeldaTemp").className=jsEstTemp;
document.getElementById("idEst220").innerHTML=jsEst220;
document.getElementById("Celda220").className=jsEst220;
document.getElementById("idEstSec").innerHTML=jsEstSec;
document.getElementById("CeldaSec").className=jsEstSec;
document.getElementById("idEstModo").innerHTML=jsEstModo;
document.getElementById("CeldaModo").className=jsEstModo;
document.getElementById("idEstDelay").innerHTML=jsEstDelayMed;
document.getElementById("CeldaDelay").className=jsEstDelayMed;
document.getElementById("idProxConm").innerHTML=jsProxConm;

if (wPagina==='IRLEARN'){
document.getElementById("idDivCr1").innerHTML=jsDivCr1;
document.getElementById("idDivCr2").innerHTML=jsDivCr2;
}
// this is to refresh the data
setTimeout("Read_XML_File(wPagina)",1000);

}

My question is if the xmlDoc is correctly created for android in the .js file

Thank you in advance
