You can turn a node list into a Perl array by just dereferencing it as an array: 
#!/usr/bin/perl
use warnings;
use strict;
use feature qw{ say };

use XML::DOM;

my $parser = 'XML::DOM::Parser'->new;

my $doc = $parser->parsefile(shift) or die $!;
my $config = $doc->getElementsByTagName('config');
my $config_attr = $config->[0]->getAttribute('logdir');
say $config_attr;

}map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,
