PHP: Manual: xml_set_notation_decl

Description

int xml_set_notation_decl_handler (int parser, string handler)

Sets the notation 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.

A notation declaration is part of the document's DTD and has the following format:
<!NOTATION name {systemId | publicId}>
See section 4.7 of the XML 1.0 spec for the definition of notation declarations.

The function named by handler must accept five parameters:

handler (int parser, string notationName, string base, string systemId, string publicId)

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

True is returned if the handler is set up, false if parser is not a parser.

There is currently no support for object/method handlers.
