in reply to how to make a package variable as c++

#Error here: Useless use of hash element in void context $singleton->{$XMLfile_name}=>$_;
something => another_thing means "something", another_thing (note the quotes, see Comma Operator for more info). Did you mean just "="?

You also seem to use $_ instead of elements in @_. Fuction arguments are in the @_ array (which is modified by shift, by the way), not in the single $_ scalar variable.

Sorry if my advice was wrong.
