how to get the correlation energy and exchange energy parts from DFT calculation?

I am not sure this information is available. To me it seems the exchange 
energy is only available separately if hartree fock or mp2 is used.
Maybe you could minimize a wave function and then make a restart from this 
calculation, where you only use the exchange or only the correlation part 
of the functional and do not minimize again.
