Hi,
I am passing the reference of a HASH to a method, which does not produce the desired result.
Refer the following code:
use XML::Simple;
my $config = XMLin("SAMLResponse with attrs.xml");
traverseHash($config);
sub traverseHash
{
my $hRef=@_;
print ref($hRef);
}
The above code produces no output, indicating that the parameter received is not a hash. However, if the type of variable $config is checked using ref() method, it clearly indicates that it is a HASH.
Please clarify this discrepancy in the result.
Thanks in advance,
Piyush
