hey all - say i have a string of numbers: 32 32 32 32 00 x y z 88 56 46
and i want to grab just x,y and z from that string? the x y z variables change, while the other numbers remain constant, so I'd like to strip those away and be left with x,y and z
how might i set that up using regexp - and is that the best way?
I am assuming it has to do with the backreference outlet.
