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

Here's my pretty simple try (without using files and just for a single page). Adjust to taste:

#!/usr/bin/perl use strict; use warnings; use LWP::RobotUA; use HTML::SimpleLinkExtor; sub grab_links { my ( $ua, $url ) = @_; my @links; my $response = $ua->get($url); if ($response->is_success) { my $extor = HTML::SimpleLinkExtor->new(); my $content = $response->content; $extor->parse($content); @links = $extor->a; # get a ref links. Check docs - these are re +lative paths. } else { die $response->status_line; } return @links; } my $visit = $ARGV[0]; my $ua = LWP::RobotUA->new('my-robot/0.1', ''); # Change th +is to suit. $ua->delay( 0.1 ); # hit every 1/10 second my @links = grab_links($ua, $visit); my %uniq; foreach ( @links ) { $uniq{$_}++; } print "Visited: ", $visit, " found these links:\n", join( "\n", keys % +uniq), "\n";

Update: this code was put here after talking to mkurtis in the CB. It appears to do most of the things mkurtis is after, so I posted it for future reference.
Most of the code was taken straight from the docs for HTML::SimpleLinkExtor, LWP::RobotUA and LWP::UserAgent.

This is the first time I've used any of those modules and it was quite cool :-)

If the information in this post is inaccurate, or just plain wrong, don't just downvote - please post explaining what's wrong.
That way everyone learns.
