[BiO BB] paup output parsing

[Ognen Duzlevski]

Hi all,

I am trying to parse out paup output such as this one:
tree PAUP_1 = [&U] (1:4,2:20,((3:14,5:200):17,4:13):24);

What I want is to extract the length for each one. The number after : is
the length

For this case:
Length of 1 will be 4
Length of 2 will be 20
Length of 3 will be 14+17+24=55
Length of 5 will be 200+17+24=241
Length of 4 will be 13+24=3

Naturally, the output gets pretty large and complicated and before I fire
up my editor and start coding: are there any tools/scripts outhere that
extract this information already and are available for download?

Thanks,
Ognen
