Writing Geospatial XML data
The GeoXml module provides the ability to convert shapes into a spatial XML document. When writing you can pass in a map instance which will result in all shapes on the map being exported. Alternatively, you can also pass in a shape, an array of shapes, a layer, a ground overlay, or GeoXmlDataSet. In this sample we will export all shapes from the map as KML and display the XML in a text area below the map.

<script type='text/javascript'>
var map;
function GetMap()
{
map = new Microsoft.Maps.Map('#myMap', {
credentials: 'Your Bing Maps Key'
});
//Add a some random data to the map.
var polygons = Microsoft.Maps.TestDataGenerator.getPolygons(3, map.getBounds(), 5, null, null, true);
map.entities.push(polygons);
var pushpins = Microsoft.Maps.TestDataGenerator.getPushpins(3, map.getBounds());
map.entities.push(pushpins);
//Load the GeoXml module.
Microsoft.Maps.loadModule('Microsoft.Maps.GeoXml', function () {
//Pass in the map to export all data on it into an XML string.
var xml = Microsoft.Maps.GeoXml.write(map, {
xmlFormat: Microsoft.Maps.GeoXmlFormat.kml,
roundLocations: true,
indentChars: ' ' //Use 4 spaces instead of \t for indenting as it looks better in the textarea.
});
//Display the XML in the text area.
document.getElementById('xmlPanel').value = xml;
});
}

If you run this sample you will see a map with some random pushpins and polygons on it, as well as a text area below the map which contains the KML markup for these shapes.
