WMS question

[Bart van den Eijnden (OSGIS)]

This can be accomplished using SLD. In a WMS GetMap request you can add 
an inline SLD using the SLD_BODY parameter, or use the SLD parameter to 
point to a URL pointing to the actual SLD XML document.

The Chameleon ExpressionBuilder widget has some code to do this or check 
out:

If a WMS layer is queryable, you can perform a WMS GetFeatureInfo 
request against it using an X and Y value in pixels, which can return a 
plain text, HTML or GML document.

Best regards,
Bart
