Detailed Description
The QDomImplementation class provides information about the features
of the DOM implementation.
This class describes the features that are supported by the DOM
implementation. Currently only the XML subset of DOM Level 1 and DOM Level 2
Core are supported.
Normally you will use the function QDomDocument::implementation() to get the
implementation object.
You can create a new document type with createDocumentType() and a new
document with createDocument().
For further information about the Document Object Model see
http://www.w3.org/TR/REC-DOM-Level-1/ and
http://www.w3.org/TR/DOM-Level-2-Core/.
For a more general introduction of the DOM implementation see the
QDomDocument documentation.
See also hasFeature() and XML.
Member Function Documentation
QDomImplementation::QDomImplementation ()
Constructs a QDomImplementation object.
QDomImplementation::QDomImplementation ( const QDomImplementation & x )
Constructs a copy of x.
QDomImplementation::~QDomImplementation () [virtual]
Destroys the object and frees its resources.
QDomDocument QDomImplementation::createDocument ( const QString & nsURI, const QString & qName, const QDomDocumentType & doctype ) [virtual]
Creates a DOM document with the document type doctype. This function also
adds a root element node with the qualified name qName and the namespace
URI nsURI.
QDomDocumentType QDomImplementation::createDocumentType ( const QString & qName, const QString & publicId, const QString & systemId ) [virtual]
Creates a document type node for the name qName.
publicId specifies the public identifier of the external subset; If you
specify QString::null as the publicId, this means that the document type
has no public identifier.
Similarly, you specify the system identifier of the external subset with systemId. If you specify QString::null as the systemId, this means that
the document type has no system identifier. Since you cannot have a public
identifier without a system identifier, the public identifier is set to
QString::null if there is no system identifier.
Other features of a document type declaration are not supported by DOM level
2.
The only way you can use a document type that was created this way, is in
combination with the createDocument() function to create a QDomDocument with
this document type.
See also createDocument().
bool QDomImplementation::hasFeature ( const QString & feature, const QString & version ) [virtual]
The function returns TRUE if QDom implements the requested version of a feature.
Currently only the feature "XML" in version "1.0" is supported.
bool QDomImplementation::isNull ()
Returns FALSE if the object was created by QDomDocument::implementation();
otherwise returns TRUE.
bool QDomImplementation::operator!= ( const QDomImplementation & x ) const
Returns TRUE if x and this DOM implementation object were created from
different QDomDocuments.
Assigns x to this DOM implementation.
bool QDomImplementation::operator== ( const QDomImplementation & x ) const
Returns TRUE if x and this DOM implementation object were created from the
same QDomDocument.
