is s40 series support XML parsing?

Hi

how to parse an XML document i.e stored in remote location

url="http://www.google.com/ig/api?weather=delhi".

i am trying to parse this XML document with the fallowing code,but i am not able to display the parsed content

// fetchReport is my java script function

function fetchReport(city)
{
url="http://www.google.com/ig/api?weather="+city;
alert(url);

request=new XMLHttpRequest();
alert("XMLHttpRequest created");
request.open('GET', url, true);
alert("Connection established");
request.send();
alert(" XMLHttpRequest request send ");

request.onreadystatechange=function()
{

if(request.readyState==4 && request.status==200)
{

alert(request.responseText);
xmlDoc=loadXMLString(request.responseText);

document.getElementById("content").innerHTML=xmlDoc.getElementsByTagName("forecast_information")[0].childNodes[0].nodeValue;

}

};

}
function loadXMLString(txt)
{
alert("inside loadXMLString");
if (window.DOMParser)
{
parser=new DOMParser();
xmlDoc=parser.parseFromString(txt,"text/xml");
}
else // Internet Explorer
{

xmlDoc=new ActiveXObject("Microsoft.XMLDOM");

xmlDoc.async=false;
xmlDoc.loadXML(txt);
}
return xmlDoc;

}

please let me know whether s40 series will support xml parsing ar not.
