When I read your previous node I started working on a Pod::Simple example since that is currently my Pod weapon of choice. However, I couldn't find an easy way to make it do what you wanted. So instead I turned it around and marked all of the code lines and then removed them from the content.

I think that the Pod::Select example above is more elegant, for this case, but here is the Pod::Simple example for the record: 

#!/usr/bin/perl -w

package MyParser;

use Pod::Simple;
@ISA = qw(Pod::Simple);
use strict;

sub new {
    my $self = shift->SUPER::new(@_);

    $self->{_lines}      = [];

    # Add a callback for code lines
    $self->code_handler (
        sub {
            my $line_num = $_[1];
            my $parser   = $_[2];

            # Replace code lines with undef.
            $parser->{_lines}->[$line_num -1] = undef;
            return;
        }
     );

    return $self;
}


#
# Override parse_lines to store a copy of the input.
#
sub parse_lines {
    my $self = shift;

    push @{$self->{_lines}}, @_;

    $self->SUPER::parse_lines(@_);
}


#
# Filter out the undef lines that replace the code lines.
#
sub pod_only {
    my $self = shift;

    my @pod  = grep {defined} @{$self->{_lines}};

    print {$self->{'output_fh'}} @pod;
    return @pod;
}


1;


#
# Back to our scheduled program.
#
package main;

use strict;

my $pod;

my $parser =MyParser->new();
   $parser->parse_file(*DATA);
   $parser->output_string(\$pod);
   $parser->pod_only();

print $pod;


__DATA__
