Writing Geospatial XML data

Bing
 

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 textarea below the map.

        //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;
        });
    }

    <textarea id="xmlPanel" style="width:800px;height:300px;"></textarea>

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