XML::LibXML::Dtd - A Class implementing Dtd Nodes

=head1 synopsis

 use XML::LibXML

 $dtd = XML::LibXML::Dtd->new($public_id, $system_id)
 $dtd = XML::LibXML::Dtd->parse_string($dtd_str)


=head1 DESCRIPTION




This class holds a DTD. You may parse a DTD from
either a string, or from an external SYSTEM
identifier.





No support is available as yet for parsing from a
filehandle.





XML::LibXML::Dtd is a sub-class of Node, so all the
methods available to nodes (particularly toString())
are available to Dtd objects.




=head2 Methods

=over 4

=item B<new>




Parse a DTD from the system identifier, and return
a DTD object that you can pass to $doc->is_valid()
or $doc->validate().



 my $dtd = XML::LibXML::Dtd->new(
                      "SOME // Public / ID / 1.0",
                      "test.dtd"
                                );
 my $doc = XML::LibXML->new->parse_file("test.xml");
 $doc->validate($dtd);
                    

=item B<parse_string>




The same as new() above, except you can parse a
DTD from a string.
