=head1 NAME
XML::Parser::Style::Objects - Objects styler parser
=head1 SYNOPSIS
use XML::Parser;
my $p = XML::Parser->new(Style => 'Objects', Pkg => 'MyNode');
my $tree = $p->parsefile('foo.xml');
=head1 DESCRIPTION
This module implements XML::Parser's Objects style parser.
This is similar to the Tree style, except that a hash object is created for
each element. The corresponding object will be in the class whose name
is created by appending "::" and the element name to the package set with
the Pkg option. Non-markup text will be in the ::Characters class. The
contents of the corresponding object will be in an anonymous array that
is the value of the Kids property for that object.
