I can dereference a tree into single level struct. But when I try and do the same with a multi level struct like below all the subFields are undef and then there is a new empty hash inserted into the tree.

Any ideas as to why my derefrencing is being treated like some kind of setter instead of a getter.

$self is a hash ref of Field passed in by argument. 
struckt subField => {
   subField1 => '$',
   subField2 => '$',
   subField3 => '$',
   subField4 => '$',  
};

struck Field => {
   field1 => 'subField',
   field2 => 'subField',
};

my @list (field1, field2);
my @subList (subField1, subField2, subField3, subField4);

if ($res->is_success)
  { 
  my $tree = $s->XMLin($res->content);

  foreach $item (@list)
  {
    foreach $subItem (@subList)
    {
      $self->$item->$subItem ( $tree->{level1}->{level2}->{$item}->{su
+bItem} );
    }
  }
} else { 
  print "GET request failed: $getURL\n";
}
