[OpenLayers-Users] Format WMSGetFeatureInfo response

[Max Stephan]

Hey michogar,

I haven´t seen your method of performing a wmsgetfeatureinfo yet. I only
know the method which is used in the geoserver-mappreviews as well which
looks like this for example:

                map.events.register('click', map, function (e) {
			document.getElementById('ausgabeContainer').innerHTML = "<div
id='einzelcontainer'><div id='headerInfo'>i</div><div id='einzelContent'>Die
Suche l&auml;uft ...</div></div>";
                    var params = {
                        REQUEST: "GetFeatureInfo",
                        EXCEPTIONS: "application/vnd.ogc.se_xml",
                        BBOX: map.getExtent().toBBOX(),
                        X: e.xy.x,
                        Y: e.xy.y,
                        INFO_FORMAT: 'application/vnd.ogc.gml',
			QUERY_LAYERS: 'bam:briefkaesten' + "," + 'bam:briefmarken' + "," +
'bam:paketstation' + "," + 'bam:telzellen',
                        Layers: 'bam:briefkaesten' + "," + 'bam:telzellen',
                        Srs: 'EPSG:900913',
                        WIDTH: map.size.w,
                        HEIGHT: map.size.h};
                   
OpenLayers.loadURL("http://141.13.60.18:8080/geoserver/wms", params, this,
setHTML, setHTML);
                    OpenLayers.Event.stop(e);
                });


In this case the answer from the server is given in GML-Format (INFO_FORMAT:
'application/vnd.ogc.gml'). That´s different to the
standard-GeoServer-method which uses "text/HTML" as answer-format. In the
setHTML-method I´m parsing that gml which gives me access to the seperate
features so that I can create an individual output (for example I can read
URLs from the Attributes and show the associated picture in the output).

How does your way work?

greets
Max Stephan
