xml_set_notation_decl_handlerSet up notation declaration handler


bool xml_set_notation_decl_handler ( resource $parser , callable $handler )

Sets the notation declaration handler function for the XML parser parser.

A notation declaration is part of the document's DTD and has the following format:

<!NOTATION <parameter>name</parameter>
{ <parameter>systemId</parameter> | <parameter>publicId</parameter>?>
See » section 4.7 of the XML 1.0 spec for the definition of notation declarations.



A reference to the XML parser to set up notation declaration handler function.


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

The function named by handler must accept five parameters:

handler ( resource $parser , string $notation_name , string $base , string $system_id , string $public_id )
The first parameter, parser, is a reference to the XML parser calling the handler.
This is the notation's name, as per the notation format described above.
This is the base for resolving the system identifier (system_id) of the notation declaration. Currently this parameter will always be set to an empty string.
System identifier of the external notation declaration.
Public identifier of the external notation declaration.

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

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

Return Values

Returns TRUE on success or FALSE on failure.
