mkurtis, I tried to mimic the behaviour you seem to expect. Try this.

Updated, for HTML::SimpleLinkExtor returns links only from first parse. 

#/usr/bin/perl -w
use strict;

use LWP::RobotUA;
use HTML::SimpleLinkExtor;

use vars qw/$http_ua $link_extractor/;

sub crawl {
    my @queue = @_;
    my %visited;
    my $a = 0;

    while(my $url = shift @queue) {
        next if $visited{$url};

        my $content = $http_ua->get($url)->content;

        open FILE, '>' . ++$a . '.txt';
        print FILE $content;
        close FILE;
        
        print qq{Downloaded: "$url"\n};

        push @queue,
        do {
                my $link_extractor = new HTML::SimpleLinkExtor;
                $link_extractor->parse($content);
                $link_extractor->a
            };
        $visited{$url} = 1;
    }
}

$http_ua = new LWP::RobotUA theusefulbot => 'bot@theusefulnet.com';

crawl(@ARGV);
