HTML::SimpleLinkExtor only gives you a list of the links in the webpage. To check if you can connect with the resource pointed to by the link I used the head function from LWP::Simple. In scalar context it returns TRUE if successful.

If you need more detailed information you have to use LWP::UserAgent:

use strict; use warnings; use LWP::UserAgent; use HTML::SimpleLinkExtor; my $agent = LWP::UserAgent->new; my $extor = HTML::SimpleLinkExtor->new(''); $extor->parse_url(''); print "Checking $_: ", $agent->head($_)->code, "\n" for $extor->links
This will give you the HTTP status code. If you replace ->code by ->message, you get a human readable message instead of the three digit code.


A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
