=head1 NAME
XML::Parser::Style::Subs - glue for handling element callbacks
=head1 SYNOPSIS
use XML::Parser;
my $p = XML::Parser->new(Style => 'Subs', Pkg => 'MySubs');
$p->parsefile('foo.xml');
{
package MySubs;
sub foo {
# start of foo tag
}
sub foo_ {
# end of foo tag
}
}
=head1 DESCRIPTION
Each time an element starts, a sub by that name in the package specified
by the Pkg option is called with the same parameters that the Start
handler gets called with.
Each time an element ends, a sub with that name appended with an underscore
("_"), is called with the same parameters that the End handler gets called
with.
Nothing special is returned by parse.
