Polymorphism is your friend - definitely subclass! This way you can define an output method and just call it on which ever object you instantiated. You could even set up a factory object that instantiates the object for you. Here is a very simple example: 
package Factory;

sub create {
   my $class = shift;
   my $obj = 'Base::' . shift;
   return $obj->new();
}

package Base;

sub output {
   my $self = shift;
   return $self->{thing};
}

package Base::Foo;
use base 'Base';

sub new {
   my $class = shift;
   my $self = { thing => 'foo' };
   return bless $self,$class;
}

package Base::Bar;
use base 'Base';

sub new {
   my $class = shift;
   my $self = { thing => 'bar' };
   return bless $self,$class;
}

package main;

my @things = (
   Factory->create('Foo'),
   Factory->create('Bar'),
);

print $_->output,$/ for @things;

Just replace Base with Resume and Foo and Bar with XML, HTML, PDF or whatever. Check out http://www.patternsinperl.com/designpatterns/factorymethod for a good read also.
