-
- XML::Parser::Style::Objects
-
- =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.
