xml_set_start_namespace_decl_handler — Set up start namespace declaration handler

Описание

bool xml_set_start_namespace_decl_handler ( resource $parser , callback $handler )

Set a handler to be called when a namespace is declared. Namespace declarations occur inside start tags. But the namespace declaration start handler is called before the start tag handler for each namespace declared in that start tag.

Список параметров

parser

A reference to the XML parser.

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 four parameters, and should return an integer value. If the value returned from the handler is FALSE (which it will be if no value is returned), the XML parser will stop parsing and xml_get_error_code() will return XML_ERROR_EXTERNAL_ENTITY_HANDLING.

handler ( resource $parser , string $user_data , string $prefix , string $uri )

parser: The first parameter, parser, is a reference to the XML parser calling the handler.
user_data
prefix
uri

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

Замечание: В качестве аргумента вместо имени функции может быть передан массив, содержащий ссылку на объект и имя метода.

Возвращаемые значения
