Also, what's the difference between using1) Control.WMSGetFeatureInfo with an infoFormat : 'application/vnd.ogc.gml', and
2) Control.GetFeature with a Protocol.WFS.fromWMSLayer(layer) ..?

Hello,I'm using Mapserver with the following PostGIS layer: http://pastie.org/5441655To give an example, here is what my data looks like: site_id site_name occurence_id occurence_name 10 sitea 123 occurenceA 10 sitea 456 occurenceB 10 sitea 789 occurenceC 10 sitea 101 occurenceD(an occurence is linked to a site, so in this case 4 occurrences are linked to "sitea".)When I click on a point on the map I would like to display all (and only) the sites name. I use a WMS getfeatureinfo for this. The problem is that I need to group data coming from the getfeatureinfo by site, otherwise the same site is displayed multiple times.I wondered if there is an easy way to do that in OpenLayers, other than returning GML, parsing it and build the DOM by hand .. .?Thank you, Julien _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users
