Parameters

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.
