Re^4: Size of an Hash reference

[dvinay]

Thanks a lot for your help,

i have one more doubt if i want to check the existence of an key in an hash reference

here is this i have tried

print Dumper \$returnvalue;
$VAR1 = \{
            ' WWN2' => ' 5678',
            ' WWN1' => ' 125689'
          };
my $string="WWN1";
if (exists $returnvalue->{$string})

to my surprise its returning false

Any clue why its happening, is my if condition correct or not

The keys in the hash start with a space, $string does not.

It's because your keys have a leading space.
