You can pass anonymous subroutines that contain references to your
object as the handlers. For example:
package My::XML::Thing;
...
sub parse {
my $self = shift;
my $parser = XML::Parser->new(Handlers => {
Start => sub { $self->parse_start_field(@_) },
Char => sub { $self->parse_char_field(@_) },
});
...
The handlers for Start and Char are closures, and contain a reference to
your object (in $self).
