$xml->isa('HASH') will not work if $xml is not blessed, so if it is a hash ref or an array ref you won't be able to use this syntax. You have to use UNIVERSAL::isa(  $xml, 'HASH') instead, calling isa as a regular sub.

Update: you might also be better off using a higher-level module like XML::Simple, which will put the data into a nice Perl data structure for you.
