xml_set_unparsed_entity_decl_handler Set up unparsed entity declaration handler intxml_set_unparsed_entity_decl_handler intparser stringhandler 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 intparser stringentityName stringbase stringsystemId stringpublicId stringnotationName parser The first parameter, parser, is a reference to the XML parser calling the handler. entityName The name of the entity that is about to be defined. base 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. systemId System identifier for the external entity. publicId Public identifier for the external entity. notationName 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. ¬e.func-callback;
