NAME
    XML::LibXML::Dtd - XML::LibXML DTD Handling

SYNOPSIS
      use XML::LibXML;

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

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 XML::LibXML::Node, so all the methods available to nodes
    (particularly toString()) are available to Dtd objects.

METHODS
    new
          $dtd = XML::LibXML::Dtd->new($public_id, $system_id);

        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);

    parse_string
          $dtd = XML::LibXML::Dtd->parse_string($dtd_str);

        The same as new() above, except you can parse a DTD from a string. Note that parsing from
        string may fail if the DTD contains external parametric-entity references with relative
        URLs.

    getName
          $publicId = $dtd->getName();

        Returns the name of DTD; i.e., the name immediately following the DOCTYPE keyword.

    publicId
          $publicId = $dtd->publicId();

        Returns the public identifier of the external subset.

    systemId
          $systemId = $dtd->systemId();

        Returns the system identifier of the external subset.
