Detailed Description

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 QXmlDTDHandler
PySide2.QtXml.QXmlDTDHandler.errorString()
Return type

unicode

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)
Parameters
  • name – unicode

  • publicId – unicode

  • systemId – unicode

Return type

bool

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

The argument name is the notation name, publicId is the notation’s public identifier and systemId is the notation’s system identifier.

If this function returns false the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.

PySide2.QtXml.QXmlDTDHandler.unparsedEntityDecl(name, publicId, systemId, notationName)
Parameters
  • name – unicode

  • publicId – unicode

  • systemId – unicode

  • notationName – unicode

Return type

bool

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

The argument 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.

If this function returns false the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.
