HTML::LinkExtor does a good amount of the work you want, indeed. To fetch pages you should use LWP::RobotUA. Checking URLs should be easy using URI. For the title and meta tags, HTML::HeadParser is the tool of choice. Finally, your loop will end up looking more like this: 
while @url {
   $page = get ( $url = shift @url )
   if(not defined $page) {
     push @error, $url
     next
   }
   push @url, match_base_url ( extract_links ( $page ) )
   push @info, [ extract_header_tags $page ]
}
print_information for @info
print_error_url for @error

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
