[OpenLayers-Users] expand on georss layer

[Don Martin]

We've got a georss example working on our site - truck tracking records from
a sql query rendered as georss.
We need a couple of other things from this layer if possible -
	1. color coded markers/icons indicating when the vehicle is next scheduled
to be available - so different markers for a particular record determined by
a field in our query (then to xml?).
	2. clicking on a marker needs to pass an id (that we can tie back to the
sql table/query) to a textbox on the page but off the map to support further
processing.

Included below is the working geoss layer call and an uninformed attempt at
a GML/georss layer (obviously not really getting it).

Would someone kindly direct me to a sample (GML or vector presumably) that
would support our needs?

working georss layer:

        function loadvehicleLayers() {
            carrier_id = document.getElementById('DDvcarrier').value;
            vehicle_ref = document.getElementById('DDvvehicle').value;
            datepass = document.getElementById('selvdateTextBox').value; 

            listname = "vehicletrack";
            filecall =
"../component/mapxml.aspx?actv="+listname+"&carv="+carrier_id+"&vehv="+vehicle_ref+"&datev="+datepass
            icon = new OpenLayers.Icon("../images/map/Pushpin.png", new
OpenLayers.Size(18,18));
            vehiclelay = new OpenLayers.Layer.GeoRSS( 'vehicle', filecall,
{'icon':icon, 'useFeedTitle':false });
            vehiclelay.events.register("loadend", window, vehicletrac);

        function vehicletrac() {
            vehiclelineLayer = new
OpenLayers.Layer.PointTrack(vehiclelay.name + " track",
                    {dataFrom:
OpenLayers.Layer.PointTrack.dataFrom.SOURCE_NODE});
            vehiclelineLayer.addNodes(vehiclelay.features);
            map.addLayer(vehiclelineLayer);
            vehiclelay.setName(vehiclelay.name + " node");
            var feature, marker;
            for (var i = vehiclelay.features.length-1; i>0; i--) {
                if (vehiclelay.features[i].data.popupContentHTML.indexOf(
                        "Untitled") != -1) {
                    vehiclelay.removeMarker(vehiclelay.markers[i]);
                }
            }
            map.raiseLayer(vehiclelay, 4);
            map.addLayer(vehiclelay);
        }
