Re: Passing additional arguments to XML::Twig handlers

If you want only constant args, you can fall back on closures:

my $greeting = "hi";

my $my_s = sub {
    my ($twig, $section) = @_;
    print $greeting || "Hello" , ", ", $section->text(), "!\n";
}

You can then pass the closure in $my_s just like a normal reference to a sub.

The args change from parse to parse, unfortunately. Closures are something I need to get more used to in general, though - thanks!	[reply]
