You should carefully study the source code of working scripts for examples of looping and matching, you will learn a lot! In the meantime pay close attention to the difference between this and your original code which lacked the 'if' condition:

foreach my $ref (@records){
 if($ref=~/URL/){
 print qq(<B>Webpage: </B><A HREF="$ref">$ref</A><br>);
 }
}
