Read Geospatial XML String
This sample shows how to read geospatial XML data stored in a string. When reading geospatial XML data using the read and readFromUrl functions you have complete control of the data, you can render it or simply extract information from it. In this sample we will render it on the map.

//Load the GeoXml module.
Microsoft.Maps.loadModule('Microsoft.Maps.GeoXml', function () {
//Parse the XML data.
var data = Microsoft.Maps.GeoXml.read(georss);
//Do something with the parsed XML data, in this case render it.
renderGeoXmlDataSet(data);
});
}
function renderGeoXmlDataSet(data) {
//Remove all existing data from the map.
map.entities.clear();
map.layers.clear();
//Add all shapes that are not in layers to the map.
if (data.shapes) {
map.entities.push(data.shapes);
}
//Add all data layers to the map.
if (data.layers) {
for (var i = 0, len = data.layers.length; i < len; i++) {
map.layers.insert(data.layers[i]);
}
}
//Add all screen overlays to the map.
if (data.screenOverlays) {
for (var i = 0, len = data.screenOverlays.length; i < len; i++) {
map.layers.insert(data.screenOverlays[i]);
}
}
if (data.summary && data.summary.bounds) {
//Set the map view to focus show the data.
map.setView({ bounds: data.summary.bounds, padding: 30 });
}

If you run this sample you will see a simple polygon that was defined in a string in GeoRSS format rendered on the map.
