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

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

tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
