[OpenLayers-Users] split WMS GetFeatureInfo results

[Roald de Wit]

One more addition: you can also use a GetFeature control with the new 
OpenLayers.Protocol.WFS.fromWMSLayer protocol.
That's probably a cleaner way, but you'd have to find out how to add 
extra paramaters like 'propertyName' and you'd still need to loop 
through the attributes and show them.
Here is a standard GetFeature example using WFS:
