in thread xml simple not a hash reference

Thanks, I am almost there. I am using the following code:

my $type = ref( $e->{mealplans}->{mealplan} ); if ($type eq "ARRAY") { $mealplans=$e->{mealtypes}->{mealtype}; for my $mealtype ( @{$e->{mealtypes}->{mealtype}} ) { $rateid = $mealtype->{rateid}; print "$mealtype"; } }

It prints out: HASH(0x27acfbc)HASH(0x27acfcc) How do I get the Array readable?

    It prints out: HASH(0x27acfbc)
    This indicates that your $mealtype variable does not hold a scalar or array, but a reference to a hash.

    The easiest way to print that is probably to use Data::Dumper:

    use Data::Dumper; print Dumper($mealtype);
      To quote perldata
      Perl has three built-in data types: scalars, arrays of scalars, and associative arrays of scalars, known as "hashes". A scalar is a single string (of any size, limited only by the available memory), number, or a reference to something (which will be discussed in perlref).
