xml_set_unparsed_entity_decl_handler

Set up unparsed entity declaration handler (PHP 3>= 3.0.6, PHP 4 )
bool xml_set_unparsed_entity_decl_handler ( resource parser, callback 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:

copy to clipboard
<!ENTITY <parameter>name</parameter> {<parameter>publicId</parameter> | <parameter>systemId</parameter>}
       NDATA <parameter>notationName</parameter>

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:

parser
The first parameter, parser, is a reference to the XML parser calling the handler.
entity_name
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.
system_id
System identifier for the external entity.
public_id
Public identifier for the external entity.
notation_name
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.

Note:

Instead of a function name, an array containing an object reference and a method name can also be supplied.
