If only the cap upstream of the regulator blew, you can usually get away without the cap if you unsolder it - the reason being that the cap just provides a smoothing role to the incoming voltage - by removing the cap that may be now providing a short circuit, you can usually see that the rest of the circuit still works if you don't have a noisy voltage source (wouldn't be a good long term solution, though).
But as MoFl says: bad news that the down stream cap blew too.
You can try it, but don't expect too much.
