[OpenLayers-Users] Popup Attribute Display format

[Marc Jansen]

Hi Cress,

Play around with the INFO_FORMAT-parameter of the 
getFeatureInfo-Request. E.g. "application/vnd.ogc.gml" would perhaps be 
better suited.

INFO_FORMAT: 'application/vnd.ogc.gml',

Afterwards look at the response and try to parse/read the servers' 
answer using a proper OpenLayers.Format. With the parsed info you can 
build any HTML you want and insert it into the popup.

Regards,
Marc
