Since you already have use Data::Dumper in your script, you could just add this line, and the contents of $data should become clear: 
print Dumper( $data );

The output from that call would show you that you reach Author entries like this: 
my @authors = @{$data->{Article}{AuthorList}{Author}};

print Dumper( \@authors );
