xml_set_notation_decl_handler — Set up notation declaration 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>?>
parserThe XML parser.
handler
If null is passed, the handler is reset to its default state.
An empty string will also reset the handler, however this is deprecated as of PHP 8.4.0.
If handler is a callable,
the callable is set as the handler.
If handler is a string,
it can be the name of a method of an object set with
xml_set_object().
This is deprecated as of PHP 8.4.0.
As of PHP 8.4.0, the callable is checked to be valid while setting the handler, not when it is called. This means that xml_set_object() must be called prior to setting a method string as the callback. However, as this behaviour is also deprecated as of PHP 8.4.0, using a proper callable for the method is recommended instead.
The signature of the handler must be:
$parser,$notation_name,$base,$system_id,$public_idparsernotation_namebase
system_id) of the notation declaration.
system_idpublic_id
Always returns true.
