Hi Nathalie,
Instead of using the split function I would personally go for a regular
expression as it allows for a lot more control over what you want to find.
Here is my solution...
#!/usr/local/bin/perl
use strict;
use warnings;
my $fh;
my %results;
open ( $fh, '<', 'temp.txt' ) or die $!;
while ( <$fh> ) {
chomp;
my $line = $_;
my $rownum = substr($line, 0, 1);
my @othernumbers;
while ( /(\d{7}-\d{7})/g ) {
push ( @othernumbers, $1 );
}
$results{$rownum} = \@othernumbers;
}
close $fh;
use Data::Dumper;
print Dumper %results;
This should print the results below:
$VAR1 = '1';
$VAR2 = [
'3206102-3207048',
'3411782-3411981',
'3660632-3661428'
];
$VAR3 = '2';
$VAR4 = [
'4481796-4482748',
'4483180-4483486'
];
And this is I believe where you wanted to go. Of course you could just
print it directly without the need for the temp variables etc but I assume
that you want to do something more with the found values then just dump
them on your screen.
Regards,
Rob
