I have to maintain some perl scripts used to validate data in dictionary entries written in XML. The validation scripts use XML::twig. There is code which counts how many quotations are associated with a definition: 
if ( my @qps = $elt->children('qp') ) {
            foreach my $qp (@qps) {
                $numOfQuots = $numOfQuots + scalar( $qp->children( qr/
+^(q|xr)$/) );
            }
        }

However what is really wanted is a count of quotations which are not suppressed, which is indicated by the q tag having an attribut supp='yes' on it. As I am fairly new to using XML::twig I am not sure how to rewrite the code above so that the count is of q elements without the supp attribute or where the supp attribute is not equal to 'yes'.
