[OpenLayers-Users] extract attributes from a geoserver wms [SEC=Unclassified]

[Miles Jordan]

The content of a GetFeatureInfo response is determined by the WMS - you have very little control over what it outputs from the client side apart from applying CSS to it.

Assuming you are using Geoserver, you can create a template for what the getFeatureInfo response should look like either on a global or per-feature type level.
