xml_set_unparsed_entity_decl_handler --  Set up unparsed entity declaration handler


int xml_set_unparsed_entity_decl_handler (int parser, string handler)

Sets the unparsed entity declaration handler function for the XML parser parser. handler is a string containing the name of a function that must exist when xml_parse() is called for parser.

This handler will be called if the XML parser encounters an external entity declaration with an NDATA declaration, like the following:

<!ENTITY name {publicId | systemId} 
        NDATA notationName>

See section 4.2.2 of the XML 1.0 spec for the definition of notation declared external entities.

The function named by handler must accept six parameters:

handler (int parser, string entityName, string base, string systemId, string publicId, string notationName)


The first parameter, parser, is a reference to the XML parser calling the handler.


The name of the entity that is about to be defined.


This is the base for resolving the system identifier (systemId) of the external entity. Currently this parameter will always be set to an empty string.


System identifier for the external entity.


Public identifier for the external entity.


Name of the notation of this entity (see xml_set_notation_decl_handler()).

If a handler function is set to an empty string, or FALSE, the handler in question is disabled.

TRUE is returned if the handler is set up, FALSE if parser is not a parser.

There is currently no support for object/method handlers. See xml_set_object() for using the XML parser within an object.
