If I understand you correctly, you could take a look at ShapeShifter to create a generic subscriber. That subscriber has access to the raw data bytes.
See also the ros_type_introspection package for some examples and convenience classes that make this sort of thing somewhat easier to do.

If It's still unclear to me why you want to do this (but then again, perhaps that is not important): but if I understand you correctly, you could take a look at ShapeShifter to create a generic subscriber. That subscriber has access to the raw data bytes.
