If you are wanting to do this to learn, good for you. But if you are wanting to do something right, check out Gisle Aas's Data::DumpXML: 
use strict;
use Data::DumpXML qw(dump_xml);

my $foo = Foo->new();
dump_xml($foo);

package Foo;

sub new {
   return bless {
      scalar => 'foobar',
      array  => [('a'..'d')],
      hash   => { bar => { baz => 'qux'}},
   }, shift;
}

If you want to know what methods a class provids, you can use UNIVERSAL::can(): 
package main;
my $no = Bar->new();
print "yes\n" if $no->can('do');

package Bar;
sub new { bless {},shift }
sub do  { print "cool\n" }
