Re: Reading and storing multiple lines from a file

You could use a hash-of-hashes: perldsc

use warnings;
use strict;

my %NX_NTF_vars;
my $sec;
while (<DATA>) {
    chomp;
    if (/^SECTION=(\w+)/) {
        $sec = $1;
    }     
    if (/^NX_NTF_/) {
        my ($key, $value) = split("=", $_);
        $NX_NTF_vars{$sec}{$key} = $value;
    }
}

use Data::Dumper;
$Data::Dumper::Sortkeys=1;
print Dumper(\%NX_NTF_vars);

__DATA__

Thanks very much for both your responses, they both seem to do the job... but how would I go about capturing the values of each in single variables? Something like: `my $crhandle = $NX_NTF_vars{'cr' -> 'NX_NTF_PERSISTENT_ID'}; my $cnthandle= $NX_NTF_vars{'cnt' -> 'NX_NTF_PERSISTENT_ID'};` [download]	[reply] [d/l]

Ah, OK, I got it now: `my $crHandle = $NX_NTF_vars{'cr'}{'NX_NTF_PERSISTENT_ID'}; my $cntHandle = $NX_NTF_vars{'cnt'}{'NX_NTF_PERSISTENT_ID'};` [download] Thanks very much for the help!	[reply] [d/l]
