Different WMS servers have different output formats for GetFeaturInfo. 
IIRC you are using GeoServer. If that is correct, you can specify the 
INFO_FORMAT to be 'application/vnd.ogc.gml', then you could pass the 
output to the OL GML reader which looks a bit like this:

var gmlReader = new OpenLayers.Format.GML();

var features = gmlReader.read(data); // assuming the result of the 
output is in the variable called data

Then you can loop through the features and change the attribute 
information any way you like and visualise it any way you want.
