Hi monks I am using XML::Simple module for parsing my attached xml data. I wrote mentioned code for fetching query data value. It is working fine. But it is giving this error “Can't use string ("GENERATE EXPRESS STATIST") as a HASH ref while "strict refs" in use” .i think this error because of “foreach my $sql ($query->{content}) {” loop on line no 42. Can you suggest some way solve this??

Thank you very much

my $val = $xmlfile->{queries}->{query}->[2]->{content};
print "$val";

            foreach my $sql ($query->{content}) {
                    print "$sql\n";
                }
        }
    }
    else {

            print "---->$query\n";
        }
