# qdomdocumenttype(3qt)

The representation of the DTD in the document tree

## NAME

QDomDocumentType - The representation of the DTD in the document tree

## SYNOPSIS

All the functions in this class are reentrant when Qt is built with thread support.\</p\>

`#include <qdom.h>`

Inherits QDomNode.

### Public Members

 **QDomDocumentType ( const QDomDocumentType & n )**\
 **QDomDocumentType & operator= ( const QDomDocumentType & n )**\

## DESCRIPTION

The QDomDocumentType class is the representation of the DTD in the document tree.

The QDomDocumentType class allows read-only access to some of the data structures in the DTD: it can return a map of all entities() and notations(). In addition the function name() returns the name of the document type as specified in the \<!DOCTYPE name\> tag. This class also provides the publicId(), systemId() and internalSubset() functions.

See also QDomDocument and XML.

## MEMBER FUNCTION DOCUMENTATION

## QDomDocumentType::QDomDocumentType ()

Creates an empty QDomDocumentType object.

## QDomDocumentType::QDomDocumentType ( const QDomDocumentType & n )

Constructs a copy of *n*.

The data of the copy is shared (shallow copy): modifying one node will also change the other. If you want to make a deep copy, use cloneNode().

## QDomDocumentType::~QDomDocumentType ()

Destroys the object and frees its resources.

## QDomNamedNodeMap QDomDocumentType::entities () const` [virtual]`

Returns a map of all entities described in the DTD.

## QString QDomDocumentType::internalSubset () const` [virtual]`

Returns the internal subset of the document type or QString::null if there is no internal subset.

See also publicId() and systemId().

## bool QDomDocumentType::isDocumentType () const` [virtual]`

This function overloads QDomNode::isDocumentType().

See also nodeType() and QDomNode::toDocumentType().

Reimplemented from QDomNode.

## QString QDomDocumentType::name () const` [virtual]`

Returns the name of the document type as specified in the \<!DOCTYPE name\> tag.

See also nodeName().

## QDomNode::NodeType QDomDocumentType::nodeType () const` [virtual]`

Returns DocumentTypeNode.

See also isDocumentType() and QDomNode::toDocumentType().

Reimplemented from QDomNode.

## QDomNamedNodeMap QDomDocumentType::notations () const` [virtual]`

Returns a map of all notations described in the DTD.

## QDomDocumentType & QDomDocumentType::operator= ( const QDomDocumentType & n )

Assigns *n* to this document type.

The data of the copy is shared (shallow copy): modifying one node will also change the other. If you want to make a deep copy, use cloneNode().

## QString QDomDocumentType::publicId () const` [virtual]`

Returns the public identifier of the external DTD subset or QString::null if there is no public identifier.

See also systemId(), internalSubset(), and QDomImplementation::createDocumentType().

## QString QDomDocumentType::systemId () const` [virtual]`

Returns the system identifier of the external DTD subset or QString::null if there is no system identifier.

See also publicId(), internalSubset(), and QDomImplementation::createDocumentType().
