Re^2: TWig handler generation

[nico38100]

Hello holli Thanks for your email, I tried what you post but it doesn't seem to work. Here my code instead of having *Data I am parsing a file . Here the code

@elements = split('-', $elements_to_treat);
    if ($subject[0] eq 'delete_node'){
           print "Delete Node ".$element."\n " if ($dbgFlag == 1);
           &delete_node(@elements,$file_to_read);
    }

sub delete_node {
#---------------------------------------------------------------------
+---------
    my ($elements,$file_to_read) = @_;
    my $del_handler = sub { $_->delete()};
    my @all_element = @{$elements};
    my $handlers = {map {$_ => $del_handler} @all_element};
    my $twig = new XML::Twig(twig_handlers => $handlers);
    $twig->parsefile($file_to_read);
    }

And here the results of my parsing which is ending in errror

Line of configuration file: delete_node:{node1-node2-node3-node4}
 Element of configuration to treat: 'node1-node2-node3-node4'
 Delete Node
Couldn't open node1:
No such file or directory at C:\Users\test\Documents\

it seems it's created a file but I don't understand why, if you have an idea ? Many Thanks

You are calling your sub with a an array as "first argument": &delete_node(@elements,$file_to_read);
But in your sub you expect an arrayref: my ($elements,$file_to_read) = @_;
You need to pass your data in as a reference. Also, don't call subs with "&". And if your learning material teaches you to, throw it away.
delete_node(\@elements,$file_to_read);

See if that fixes it.
