Sometimes it would be useful to have the data for map, e.g. for markers, to reside on a separate file. In this article, an example is presented, using which you can yourself utilize a separate XML file for creating map content. The example will use Javascript and jQuery.


  • Nokia Maps API supported web browser (basically any modern web browser).
  • JQuery downloaded and installed.
  • Change the directory names for your own version of the example, if needed.

Example code

Note that the example code leaves you room to implement your own infoBubbles and some other functionality is there if you need it, otherwise you can remove it; for e.g. the behaviour of the map and availability of components. Feel free to copy and modify for your own purposes!

// This function gets passed the marker XML data file name

//Read the name, address, latitude and longitude for each Marker
var name = $(this).find('name').text();
var address = $(this).find('address').text();
var lat = $(this).find('lat').text();
var lng = $(this).find('lng').text();
//Used for testing:
//alert("Name:"+name+" Address:"+address+" Lat:"+lat+" Lon:"+lng);
//Put each marker on the map as the data has been read.
markerCoords = new nokia.maps.geo.Coordinate(parseFloat(lat), parseFloat(lng));
marker = new nokia.maps.map.StandardMarker(markerCoords,
{text:name, brush:"#FF69B4", pen:"#09F911", textPen:"#00009C", shape: "star"});
// Used for testing:
// myInfoBubbles.addBubble(name, markerCoords);
// counter ++ 1;
// alert(counter);
// Add the marker container .
// Zoom into the markers.
alert("Markers have been loaded. Hit OK to zoom the map into the area covering the markers.");
map.zoomTo(container.getBoundingBox(), false);

Example XML file

<?xml version="1.0"?>
<address>ADDRESS 1</address>
<address>ADDRESS 2</address>
<address>ADDRESS 3</address>
<address>ADDRESS 4</address>
<address>ADDRESS 5</address>
<address>ADDRESS 6</address>
<address>ADDRESS 7</address>
<address>ADDRESS 8</address>


Edit the script and file for your own purposes, hope you find this article useful.

Microsoft XP Pro and the following browsers:

  • Opera 5.0.5 & Firefox 5.0
