詳細描述

If an application needs information about notations and unparsed entities, it can implement this interface and register an instance with QXmlReader::setDTDHandler ().

Note that this interface includes only those DTD events that the XML recommendation requires processors to report, i.e. notation and unparsed entity declarations using notationDecl () 和 unparsedEntityDecl () 分彆。

[virtual noexcept] QXmlDTDHandler:: ~QXmlDTDHandler ()

Destroys the DTD handler.

[pure virtual] QString QXmlDTDHandler:: errorString () const

The reader calls this function to get an error string if any of the handler functions returns false .

[pure virtual] bool QXmlDTDHandler:: notationDecl (const QString & name , const QString & publicId , const QString & systemId )

The reader calls this function when it has parsed a notation declaration.

自變量 name is the notation name, publicId is the notation's public identifier and systemId is the notation's system identifier.

若此函數返迴 false the reader stops parsing and reports an error. The reader uses the function errorString () to get the error message.

[pure virtual] bool QXmlDTDHandler:: unparsedEntityDecl (const QString & name , const QString & publicId , const QString & systemId , const QString & notationName )

The reader calls this function when it finds an unparsed entity declaration.

自變量 name is the unparsed entity's name, publicId is the entity's public identifier, systemId is the entity's system identifier and notationName is the name of the associated notation.

若此函數返迴 false the reader stops parsing and reports an error. The reader uses the function errorString () to get the error message.
