## Detailed Description

Each `DOMDocument` has a `doctype` attribute whose value is either `null` or a `DOMDocumentType` object.

The `DOMDocumentType` interface in the DOM 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 schema efforts on DTD representation are not clearly understood as of this writing.

The DOM Level 2 doesn't support editing `DOMDocumentType` nodes.

See also the Document Object Model (DOM) Level 2 Core Specification.

## Constructor & Destructor Documentation

## DOMDocumentType()

DOMDocumentType::DOMDocumentType | ( |  | ) |

protected

## ~DOMDocumentType()

virtual DOMDocumentType::~DOMDocumentType | ( |  | ) |

virtual

Destructor.

## Member Function Documentation

## getEntities()

virtual DOMNamedNodeMap * DOMDocumentType::getEntities | ( |  | ) | const

pure virtual

A `DOMNamedNodeMap` containing the general entities, both external and internal, declared in the DTD.

Parameter entities are not contained. Duplicates are discarded. For example in: `<!DOCTYPE
ex SYSTEM "ex.dtd" [ <!ENTITY foo "foo"> <!ENTITY bar
"bar"> <!ENTITY bar "bar2"> <!ENTITY % baz "baz">
]> <ex/>
` the interface provides access to `foo` and the first declaration of `bar` but not the second declaration of `bar` or `baz`. Every node in this map also implements the `DOMEntity` interface.
The DOM Level 2 does not support editing entities, therefore `entities` cannot be altered in any way.

Since
  DOM Level 1

## getInternalSubset()

virtual const XMLCh * DOMDocumentType::getInternalSubset | ( |  | ) | const

pure virtual

The internal subset as a string, or `null` if there is none.

This is does not contain the delimiting square brackets.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.

Returns
  The internal subset as a string.

Since
  DOM Level 2

## getName()

virtual const XMLCh * DOMDocumentType::getName | ( |  | ) | const

pure virtual

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

Since
  DOM Level 1

## getNotations()

virtual DOMNamedNodeMap * DOMDocumentType::getNotations | ( |  | ) | const

pure virtual

A `DOMNamedNodeMap` containing the notations declared in the DTD.

Duplicates are discarded. Every node in this map also implements the `DOMNotation` interface.
The DOM Level 2 does not support editing notations, therefore `notations` cannot be altered in any way.

Since
  DOM Level 1

## getPublicId()

virtual const XMLCh * DOMDocumentType::getPublicId | ( |  | ) | const

pure virtual

Get the public identifier of the external subset.

Returns
  The public identifier of the external subset.

Since
  DOM Level 2

## getSystemId()

virtual const XMLCh * DOMDocumentType::getSystemId | ( |  | ) | const

pure virtual

Get the system identifier of the external subset.

Returns
  The system identifier of the external subset.

Since
  DOM Level 2
