Hi Rolf,

thanks for your reply.

But maybe you should care to define _handler within the scope of your private $_parse... variables to have a proper closure?
I believe you are right. I have come up with the following code:

my $_parse_handler = sub { my $self = shift; my $function = shift . '0'; # installed handlers my $_parse_element_configuration0 = $_parse_element_configuration; my $_parse_element_machines0 = $_parse_element_machines; eval "\$$function"; }; [...] my $handler = $self->$_parse_handler("_parse_element_" . $element->nam +e() ); $self->$handler($element);
Anyway I am getting the impression I am trying to bend the language to something it was not designed to do.

Kind regards,
s.fox

    Ugh... :-|

    Look now this really doesn't make much sense anymore.

    I was under the impression that you also need to call the handlers manually as private methods??? (they are now restricted to the sub)

    If not _please_ use dispatch tables!

    Cheers Rolf
