I'm attempting to extract numbers from codes in this generalised format (always begin with MD:Z: but what follows is variable):

MD:Z:4C3C7C0T2^T9C44

Desired output (separate array elements):

4
3
7
0
2
9
44

As I need to maintain positional information and length of each number (i.e. it must be clear that 44 = 44 and not the product of something like 4T4 after screening out letters) i've tried to use split:

my @test = split((/\D/g), $input);

To split on any non-number; however this returns a set of leading empty array values arising from the consecutive matches on 'MD:Z:'. Is there a way to suppress these or a better way to go about getting the desired result?
