In that case:

use strict; use warnings; use Test::More tests => 1; my @array1 = ('foo', 'bar'); my @array2 = (" foo\n", ',bar,'); my @clean = map { s/[\s,]//mg; $_ } @array2; is_deeply \@clean, \@array1;

Alter the map to your precise requirements. See also How to ask better questions using Test::More and sample data for future reference.

Addendum: if you don't want or need to keep your "dirty" array you could modify it in-place instead:

use strict; use warnings; use Test::More tests => 1; my @array1 = ('foo', 'bar'); my @array2 = (" foo\n", ',bar,'); s/[\s,]//mg for @array2; is_deeply \@array2, \@array1;

Addendum 2: Note the reply by AnomalousMonk (++) who correctly points out that the map already modifies @array2 and that using /r will prevent that.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
