just want to ask if there is a better way of doing this
That depends on what makes one solution "better" than another and also how representative your sample set is.
use strict;
use warnings;
use Test::More;
my @set = (
{
file => '-/yf/-/22211_01_09_2000_XYz.pdf',
zip => '22211'
},
{
file => '_/gt/-/02239_04_04_1989_PkW.pdf',
zip => '02239'
},
{
file => '-/xy/-/02239_04_04_1989_PkW.pdf',
zip => '02239'
},
);
plan tests => 2 * @set;
for my $datum (@set) {
is zip_substr ($datum->{file}), $datum->{zip}, "Substr for $datum-
+>{file}";
is zip_regex ($datum->{file}), $datum->{zip}, "Regex for $datum-
+>{file}";
}
sub zip_substr {
return substr (shift, 7, 5);
}
sub zip_regex {
my ($zip) = shift =~ m#/(\d{5})_#a;
return $zip;
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
