Hi there, a friend of mine has been struggling with an aspect of XML::Twig. He wants to be able to call private methods on his object from within the handlers. However the problem is that the handler params are the $twig and the element.
The solution i suggested is as follows, where the create_sub method is called which then creates a reference to $self before it is assigned to the handler.
Is this the correct way to do this? Or can someone suggest a better way.
#!/usr/bin/perl -w
use warnings;
use strict;
package Stupid;
{
use XML::Twig;
sub new {
my ( $caller, $args ) = @_;
my $class = ref($caller) || $caller;
my $self = {};
$self->{a_note} = "This should print something\n";
bless $self, $class;
my $code_ref = $self->create_sub;
my $t = XML::Twig->new( twig_handlers => { 'a/b' => $code_ref
+} );
my $xml = "<a><b>3</b><c>4</c></a>";
$t->parse($xml);
$t->flush;
}
sub create_sub {
my $hidden_self = shift;
return sub {
my ( $self, $t ) = @_;
print ref($self) . "\n";
print ref($t) . "\n";
print $t->text;
print "\n\n";
$hidden_self->gah();
};
}
sub gah {
my $self = shift;
print ref($self) . "\n";
print "$self->{a_note}\n";
}
};
my $s = Stupid->new();
