Re: Handler communication in XML::Twig

Indeed you can pass closures to new.

Have a look at Simon Cozens' Achieving Closure, which explains the process in great detail.

Basically you can do this:

my $t= XML::Twig->new( twig_handlers => { foo => sub { my_handler( @_,
+ @HOGS) } });
# ...
sub my_handler
  { my( $t, $elt, @HOGS)= @_; # I would probably pass \@HOGC though

Do you use it that way or are you just confirming the possible? I'm after the method good X'T users use. I don't know how heavy the twig object and whether it would be preferred to retain the existing object.	[reply]

I use it a lot that way. I have never benchmarked the creation of the object itself, as I the type of code I write rarely parses a lot of files.	[reply]
