function addSymbol() {
if (omap.map.getLayer("symbolLayer") == null) {
omap.map.addLayer(gLayer);
omap.map.infoWindow.resize(760, 425);
}
gLayer.clear();
function ajaxRequest(){
var activexmodes=["Msxml2.XMLHTTP", "Microsoft.XMLHTTP"] 
if (window.ActiveXObject){ 
for (var i=0; i<activexmodes.length; i++){
try{
return new ActiveXObject(activexmodes[i])
}catch(e){ }
}
}
else if (window.XMLHttpRequest) 
return new XMLHttpRequest()
else
return false
}
 
var mygetrequest=new ajaxRequest()
mygetrequest.onreadystatechange=function(){
if (mygetrequest.readyState==4){
if (mygetrequest.status==200 || window.location.href.indexOf("http")==-1){
var books=eval("("+mygetrequest.responseText+")") //retrieve result as an JavaScript object
var rssentries=books.places
var output = ""
var xCoo = ""
var yCoo= ""
for (var i=0; i<rssentries.length; i++){
output += rssentries[i].name
xCoo += rssentries[i].x_coordinate
yCoo += rssentries[i].y_coordinate
}
document.getElementById("result").innerHTML = output
var stX = xCoo
var stY = yCoo
var pt = new esri.geometry.Point(stX, stY, omap.map.spatialReference);
var attr = { "PlaceName": " Singapore", "PlaceAddr": "addr" };
var strImage = "http://www.rw-designer.com/i/download48b.png";
var symbol = new esri.symbol.PictureMarkerSymbol(strImage, 25, 25);
var infoTemplate = new esri.InfoTemplate();
infoTemplate.setContent();
var graphic = new esri.Graphic(pt, symbol, attr, infoTemplate);
gLayer.add(graphic);
}
else{
alert("An error has occured making the request")
}
}
}
mygetrequest.open("GET", "HTMLPage3.htm", true)
mygetrequest.send(null);
}
dojo.addOnLoad(addSymbol);
