Detailed Description露

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

class PySide2.QtXml.QXmlDTDHandler露
PySide2.QtXml.QXmlDTDHandler.errorString()露
Return type:

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

PySide2.QtXml.QXmlDTDHandler.notationDecl(name, publicId, systemId)露
Parameters:
