Re: Matching hyphens in file path to extract zip code

in reply to Matching hyphens in file path to extract zip code

Is the ZIP code always at the beginning of the filename? You can use the core module File::Basename to strip off the path:

use warnings;
use strict;
use File::Basename qw/fileparse/;

my @files = ( '-/yf/-/22211_01_09_2000_XYz.pdf',
    '_/gt/-/02239_04_04_1989_PkW.pdf',
    '-/xy/-/02239_04_04_1989_PkW.pdf' );

for my $file (@files) {
    my $bn = fileparse($file);
    my ($zip) = $bn =~ /^(\d{5})\D/;
    print "$file => $zip\n";
}

    I like that option too, just a little more code.

      just a little more code

      Not significantly, I just wrote it more verbosely.

      use File::Basename;
my ($zip) = fileparse($file) =~ /^(\d{5})\D/;

        I have to say that is makes the code cleaner and less prone to errors with a long regexp. Thank you!
