I can’t pretend to have really understood hash references, and this problem may be that my lack of understanding is causing me to try to do something that is not natural. Anyway, I am being returned a hash reference from a soap request, and am trying to retrieve an individual hash value.

I can iterate through the hash, and get the value I require, but cannot retrieve it directly; I’m assuming this should be possible.

All the commented out stanzas below work, but I would like to do something like the final uncommented stanza.

my $soap = SOAP::Lite->uri( $_[1] )->proxy( $_[2] )->getAllBrokerInfo(
+);
my @brokerInfos = @{ $soap->result };
for ( $i = 0 ; $i < @brokerInfos ; $i++ ) {
    $broker = @brokerInfos[$i];

    #Get all values for each Broker - works
            #my @values = values %$broker;
    #foreach my $value (@values){print "$value\n";}

    #Get all keys for each Broker - works
    #my @keys = keys %$broker;
    #foreach my $key (@keys){print "$key\n";}

    #Get the values for all keys for each Broker - works
    #while (($key,$value) = each(%$broker)) {
    #    print "$key $value\n";
    #}

    #Get the value for key engineWeight by iterating through all keys 
+- works
    while (($key,$value) = each(%$broker)) {
        if ( $key eq "engineWeight" ) {
            print "$key $value\n";
        }
    }

    #Just get value for engineWeight for each Broker - does not work
    print "%$brokers{'engineWeight'}\n";
}

The output from this script is simply

(there are five Brokers)

Any help very much appreciated.
