Re^2: xml simple not a hash reference

[Noverast]

Thank you for the responses. This is my code:

my $results = $res->content;
$xml = new XML::Simple (KeyAttr => [],suppressempty => 1,ForceArray =>
+ ['roomtype']);
$data = $xml->XMLin("$results");

foreach $e (@{$data->{data}->{bb}->{roomtypes}->{roomtype}}){
$roomtypename=$e->{roomtypename};
$rateid=$e->{mealtypes}->{mealtype}->{rateid};
}

I only receive the error when trying to get the value of rateid for the mealtype, if it is more than one, and I don't know how to loop through the mealtypes

I don't know how to loop through the mealtypes

The same way you're looping through the roomtypes:

    for my $mealtype ( @{$e->{mealtypes}->{mealtype}} ) {
        $rateid = $mealtype->{rateid};
    }

but don't forget to apply ForceArray to mealtype, too; or check with ref if $e->{mealtypes}->{mealtype} is an array reference, and only loop in that case (otherwise, you'd get an error if there's only one mealtype entry, in which case XML::Simple (without ForceArray in effect) would not create an extra array...)

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);

This is what I am getting

$VAR1 = { 'defaultmealplan' => 'true', 'rates' => { 'pax3' => '1180.00
+', 'pax2' => '930.00', 'pax4' => '1405.00', 'pax1' => '550.00' }, 'me
+alplandesc' => 'Bed & Breakfast', 'rateid' => '6' };

$VAR1 = { 'rates' => { 'pax3' => '850.00', 'pax2' => '700.00', 'pax4' 
+=> '975.00', 'pax1' => '450.00' }, 'mealplandesc' => 'Self-catering',
+ 'rateid' => '7' };

[Noverast]

It is sorted out now! Thank you very much for all the help

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

my $type = ref( $e->{mealtypes}->{mealtype} );

if ($type eq "ARRAY")
{

    for my $mealtype ( @{$e->{mealtypes}->{mealtype}} ) {
        $rateid = $mealtype->{rateid};
        
        print "$mealtype";
    }
}

However now I getting HASH(0x279d04c)HASH(0x279d05c). How do get the array in a readable state?
