Perl Hash access
Suppose I have a hash:


Code:
       my %table1 = (
                    'Sam' =>  {
                                'Company'       => 'XYZ',
                                'Post'          => 'Software Engineer',
                                'Skills'        => 'Perl',
                                },

                    'Mark' =>{
                                'Company'       => {
                                                       'Microsoft' => 'CMMi 5',
                                                       'Persistent'=> 'CMMi 4',
                                                       'TCS'       => 'CMMi 5',
                                                   },
                                'Post'          => 'Manager',
                                'Skills'        => 'Management',
                                },

                    'Debby'       => ['Shell', 'Perl, 'Python', 0, 5],
                    ['X', 'Y']  => ['A', 'B'],
                    );


And I want to access the array containing X and Y, how to access them in Perl?

hash::case::lower

Hash::Case::Lower(3pm)					User Contributed Perl Documentation				    Hash::Case::Lower(3pm)

NAME

       Hash::Case::Lower - hash with enforced lower cased keys

INHERITANCE

	Hash::Case::Lower
	  is a Hash::Case
	  is a Tie::StdHash

SYNOPSIS

	use Hash::Case::Lower;
	tie my(%lchash), 'Hash::Case::Lower';
	$lchash{StraNGeKeY} = 3;
	print keys %lchash;  # strangekey

DESCRIPTION

       Hash::Case::Lower extends Hash::Case, which lets you play various trics with hash keys. In this implementation, the fake hash is case
       insensitive and the keys stored in lower-case.

METHODS

   Constructors
       $obj->addHashData(HASH)
	   See "Constructors" in Hash::Case

       $obj->addPairs(PAIRS)
	   See "Constructors" in Hash::Case

       $obj->setHash(HASH)
	   See "Constructors" in Hash::Case

       tie(HASH, 'Hash::Case::Lower', [VALUES,] OPTIONS)
	   Define HASH to have only lower cased keys.  The hash is initialized with the VALUES, specified as ref-array (with key value pairs) or
	   ref-hash.  Currently, there are no OPTIONS defined.
