XMLParserItf Interface CATISAXDTDHandler

Usage: you can freely reimplement this interface.

interface CATISAXDTDHandler

Interface to receive notification of basic DTD-related events.

If a SAX application needs information about notations and unparsed entities, then the application implements this interface and registers an instance with the SAX parser using the parser's method. The parser uses the instance to report notation and unparsed entity declarations to the application.

The SAX parser may report these events in any order, regardless of the order in which the notations and unparsed entities were declared; however, all DTD events must be reported after the document handler's event, and before the first event.

It is up to the application to store the information for future use (perhaps in a hash table or object tree). If the application encounters attributes of type "NOTATION", "ENTITY", or "ENTITIES", it can use the information that it obtained through this interface to find the entity and/or notation corresponding with the attribute value.

The class provides a default implementation of this interface, which simply ignores the events.

Method Index

o NotationDecl(CATUnicodeString&,CATUnicodeString&,CATUnicodeString&): Receives notification of a notation declaration event.
o UnparsedEntityDecl(CATUnicodeString&,CATUnicodeString&,CATUnicodeString&,CATUnicodeString&): Receives notification of an unparsed entity declaration event.

Methods

o NotationDecl

public virtual NotationDecl(	const	`iName`,
	const	`iPublicId`,
	const	`iSystemId`)

Receives notification of a notation declaration event.

It is up to the application to record the notation for later reference, if necessary.

At least one of publicId and systemId must be non-empty.

If a system identifier is present, and it is a URL, the SAX parser must resolve it fully before passing it to the application.

Parameters:

iName: The notation name.
iPublicId: The notation's public identifier (can be an empty
iSystemId: The notation's system identifier (can be an empty

Errors Returned:

Error Class	Error Id	Description
	XMLParserERR_2000	The method can raise a CATSAXException
	XMLParserERR_2002	The method can raise a CATSAXParseException

o UnparsedEntityDecl

public virtual UnparsedEntityDecl(	const	`iName`,
	const	`iPublicId`,
	const	`iSystemId`,
	const	`iNotationName`)

Receives notification of an unparsed entity declaration event.

Note that the notation name corresponds to a notation reported by the event. It is up to the application to record the entity for later reference, if necessary.

If the system identifier is a URL, the parser must resolve it fully before passing it to the application.

Parameters:

iName: The unparsed entity's name.
iPublicId: The entity's public identifier (can be an empty
iSystemId: The entity's system identifier (it must always have one).
iNotationName: name The name of the associated notation.

Errors Returned:

Error Class	Error Id	Description
	XMLParserERR_2000	The method can raise a CATSAXException
	XMLParserERR_2002	The method can raise a CATSAXParseException
