I have an OpenLayers map (that you can find here, use the blue search area) that reads in a KML string that is written from Perl using data from oracle. It reads the KML like this:

var vector_Layer = new OpenLayers.Layer.Vector("Search Results");

function GetFeaturesFromKMLString (strKML) {
    var format = new OpenLayers.Format.KML({
    'internalProjection': new OpenLayers.Projection("EPSG:900913"),
    'extranalProjection': new OpenLayers.Projection("EPSG:4326")    
    });
    return format.read(strKML);
};

vector_Layer.addFeatures(GetFeaturesFromKMLString('$newkml'));

The problem I've found is that not all of the features are displayed. For example If I search for Edinburgh only the first three features are displayed from a KML with 11 features. The KML produced where you search for Edinburgh is like this:

Has anyone had a problem like this before and do you know if it is an issue with the KML or with OpenLayers?

  • are you sure the output kml is valid?

At least one issue is that you've got extranalProjection in your code rather than externalProjection.

  • thanks, you're right but it doesn't fix the problem Jul 31, 2013 at 13:59

I've fixed it. It turned out that '&'s in the database were causing errors. running a perl substitution that replaces them with & fixed it
