# class DocumentType

###

Module | khtml
Namespace | DOM
Class | DocumentType
Inherits | DOM::Node

Each Document has a doctype attribute whose value is either null or a DocumentType object. The DocumentType interface in the DOM Level 1 Core provides an interface to the list of entities that are defined for the document, and little else because the effect of namespaces and the various XML scheme efforts on DTD representation are not clearly understood as of this writing.

The DOM Level 1 doesn't support editing DocumentType nodes.

### methods

- DocumentType ( )

  returns ctor

- DocumentType (other)

  returns ctor

  Argument | Type | Default
  --- | --- | ---
  other | DOM.DocumentType |

- DocumentType (other)

  returns ctor

  Argument | Type | Default
  --- | --- | ---
  other | DOM.Node |

- DocumentType (impl)

  returns ctor
  Not implemented

  Argument | Type | Default
  --- | --- | ---
  impl | DocumentTypeImpl |

- entities ( )

  returns DOM.NamedNodeMap

  A NamedNodeMap containing the general entities, both external and internal, declared in the DTD. Duplicates are discarded. For example in: <!DOCTYPE ex SYSTEM "ex.dtd" [ <!ENTITY foo "foo"> <!ENTITY bar "bar"> <!ENTITY % baz "baz"> ]> <ex/> the interface provides access to foo and bar but not baz . Every node in this map also implements the Entity interface.

  The DOM Level 1 does not support editing entities, therefore entities cannot be altered in any way.

- internalSubset ( )

  returns DOM.DOMString

  Introduced in DOM Level 2

  The internal subset as a string.

  Note: The actual content returned depends on how much information is available to the implementation. This may vary depending on various parameters, including the XML processor used to build the document.

- name ( )

  returns DOM.DOMString

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

- notations ( )

  returns DOM.NamedNodeMap

  A NamedNodeMap containing the notations declared in the DTD. Duplicates are discarded. Every node in this map also implements the Notation interface.

  The DOM Level 1 does not support editing notations, therefore notations cannot be altered in any way.

- publicId ( )

  returns DOM.DOMString

  Introduced in DOM Level 2

  The public identifier of the external subset.

- systemId ( )

  returns DOM.DOMString

  Introduced in DOM Level 2

  The system identifier of the external subset.
