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);
