Trying to extract info from an array or hash that is inside multiple hash and array structure in a perl module generated by doxygen. I can extract most everything except what is inside detailed -> doc -> params -> parameters in following DoxyDocs1.pm

Uncomment commented sections to see data trying to extract

Including small sample of code

#!/bin/perl
use Data::Dumper;
use warnings;
require "DoxyDocs1.pm";
print "API Content Analyzer\n";
&GenerateClassInfo($doxydocs->{classes});
sub GenerateClassInfo()
{
    my ($classes) = @_;    
    foreach my $class (@$classes) {
        print "\nClass name is: $class->{name}\n";
        foreach my $pubmeth (@{$class->{public_methods}->{members}}) {
           print "\n" if exists $pubmeth->{name};
           print "\tpublic methods include: $pubmeth->{name}\n";
           my ($key, $pmcontent) = each (@{$pubmeth->{detailed}->{doc}
+});
           print "\t\tdescription: $pmcontent->{content}\n" if exists 
+$pmcontent->{content};
           # foreach my $pmp (@{$pubmeth->{detailed}->{doc}}) {
             # print "\t\t";
             # print Dumper($pmp);
           # }
           print "\t\tkind: $pubmeth->{kind}\n";
           print "\t\ttype: $pubmeth->{type}\n" if exists $pubmeth->{t
+ype};
        }
        foreach my $privmeth (@{$class->{private_methods}->{members}})
+ {
            print "\n" if exists $privmeth->{name};
            print "\tprivate methods include: $privmeth->{name}\n";
            my ($key, $pmcontent) = each (@{$privmeth->{detailed}->{do
+c}});
            print "\t\tdescription: $pmcontent->{content}\n" if exists
+ $pmcontent->{content};
            # foreach my $info (@{$privmeth->{detailed}->{doc}}) {
             # print "\t\t";
             # print Dumper($info);
            # }
            print "\t\tkind: $privmeth->{kind}\n";
            print "\t\ttype: $privmeth->{type}\n" if exists $privmeth-
