Solution #1: 
   use strict;
   use warnings;

   $/ = "<br /><br />";

   while(<DATA>) {
      chomp;
      my @record = split(/<br \/>/);
      print "@record\n" if (@record == 3);
   }

   __DATA__
Name1<br />Address1<br /><br />Name2<br />Address2<br />URL2<br /><br 
+/>Name3<br />Address3<br />URL3<br /><br />Name4<br />Address4<br /><

         next;
      }
      $record[++$i] = $_;
      print "@record\n" if ($i == 2);
