Something like this (untested):
var vectors = new OpenLayers.Layer.Vector("GeoRSS", {
strategies: [new OpenLayers.Strategy.Fixed()],
protocol: new OpenLayers.Protocol.HTTP({
url: "http://yoursite.com/path/to/your/GeoRSS";,
format: new OpenLayers.Format.GeoRSS()
}),
eventListeners: {
loadend: function() {
if (vectors.features.length === 0) {
alert("No features were loaded. Is your GeoRSS file valid?");
}
}
}
});
