The WMSGetFeatureInfo control uses a WMS query to get information about a point on the map. The information may be in a display-friendly format such as HTML, or a machine-friendly format such as GML, depending on the server’s capabilities and the client’s configuration. This control handles click or hover events, attempts to parse the results using an OpenLayers.Format, and fires a ‘getfeatureinfo’ event with the click position, the raw body of the response, and an array of features if it successfully read the response.
