Re: Extraction of letters from a string

[hippo]

I have the following string

A1=<m,n>:<p,q>:<s,t>...go on

I have to extract values m,n,p,q,s,t from the above string. How do i do it?.

You could use m// to match them:

#!/usr/bin/env perl 
use strictures;
my @v = 'A1=<m,n>:<p,q>:<s,t>...go on' =~ /[mnpqst]/g;

here the m,n,p,q... are numbers which can change based on the user, so writing a regex just to hardcode with numbers won't be a good idea i guess

How was m,n,p etc. supposed to represent digits? Anyway, if you want to match digits, match digits:

#!/usr/bin/env perl 
use strictures;
my @v = 'A1=<9,8>:<7,6>:<5,4>...go on' =~ /\d/ag;

Hi, I have one doubt , what should be changed if double or triple digits are to be considered , as of now the above mentioned code (your solution) splits 10 as 1 0
