Here is what I am trying to get work: 
my @names          = @{ $sth->{NAME} };
    
    my @ordered_values = ();
    while ( my $row = $sth->fetchrow_hashref ) {
        @ordered_values = @{$row}{@names};
    }
        print Dumper(\@names);
        print Dumper(\@ordered_values);
    my $xs =
      XML::Simple->new( keyattr => {[cdr =>'npa' ]}, rootname => 'data
+set' );

    my $cgi = CGI->new;
    print $cgi->header('text/xml');
    print XMLout( \@ordered_values );

And here is the response from the Dumper: 
$VAR1 = [
          'NPA',
          'GC_ID',
          'I_TG_NAME',
          'E_TG_NAME',
          'DN',
          'STATE'
        ];
$VAR1 = [
          AAAABUcKyqQhEAABI34stA.4515613,
          '989',
          OQ-OZDN-D-UHMC-UHMC-0939,
          MQ-MTBO-T-CCDPN-FTQ-1737,
          9895555555,
          MI
        ];

So @names is correct, but I cannot get the column names into the element tags correctly. The ordered_values array also keeps getting overwritten, as the print statement only pulls up that last record of the query results, when there is like 500. So how do I get the values for @names as the element tags instead of anon?
