xml_set_notation_decl_handler — Set up notation declaration handler

xml_set_notation_decl_handler ( XMLParser $parser , callable $handler ) : bool

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 [http://www.w3.org/TR/1998/REC-xml-19980210#Notations » section 4.7 of the XML 1.0 spec] for the definition of notation declarations.

parser

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

handler

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 ( XMLParser $parser , string $notation_name , string $base , string $system_id , string $public_id )

parser: The first parameter, parser, is a reference to the XML parser calling the handler.
notation_name: This is the notation's name, as per the notation format described above.
base: 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_id: System identifier of the external notation declaration.
public_id: 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.

Returns TRUE on success or FALSE on failure.
