Detailed Description

TheQXmlDTDHandler class provides an interface to report DTD content of XML data.

If an application needs information about notations and unparsed entities, it can implement this interface and register an instance withQXmlReader::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 usingnotationDecl() andunparsedEntityDecl() respectively.
