( #3333=superdoc: print w/replies, xml ) Need Help??

I'd use List::Compare (though I'm not sure I like its object-oriented interface):

#!/usr/bin/perl use strict; use warnings; use feature qw/say/; use List::Compare; use List::MoreUtils qw/uniq/; my %hash1 = ("abc" => [1, 2, 3, 4]); my %hash2 = ("abc" => [1, 3, 5, 7]); $, = ","; foreach my $key (uniq (keys %hash1, keys %hash2)) { my $lc = List::Compare->new($hash1{$key} // [], $hash2{$key} // [] +); say $lc->get_Lonly; # elements only in $hash1{$key} say $lc->get_Ronly; # elements only in $hash2{$key} }

Title:
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.
