When you run XML::Parser using the Start, End and Char handlers, the parameters you get out are predetermined: the object, the tag & a hash of attributes. I guess this means you can't pass arguments to the handlers then, eg
my $p = new XML::Parser (Handlers => {Start => \&hdl_start(@arr), etc}
+);

However, the following seems to be working fine for me (obviously it doesn't do anything, but it shows that the variables are being set from the subroutine), and I'm a bit concerned about why:

use strict;
use XML::Parser;

my ($tag, $name);
my $p = new XML::Parser (Handlers => {Start => \&hdl_start,
                                      Default => \&hdl_def});
$p->parsefile('test.xml');
print "$tag, $name\n";

sub hdl_start {
  my ($p, $elt, %atts) = @_;
  $tag = $elt;
  $name = $atts{'name'};
}

sub hdl_def { }

Can someone who knows about scope tell me if I'm doing a very bad thing?
