Let's assume that you have your parameters from CGI.pm. Then, you can do something like the following:

my @params = $cgi->param();

foreach my $param ( @params ) {
   if ( $cgi->param( $param ) ) {
        print "<META NAME=\"$param\" CONTENT=\"", 
             $cgi->param( $param ), "\">";
   }
}

It's not what you know, but knowing how to find it if you don't know that's important
