xml_set_start_namespace_decl_handler

(PHP 4 >= 4.0.5, PHP 5, PHP 7)

Set up start namespace declaration handler

bool xml_set_start_namespace_decl_handler ( resource $parser, callable $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.

Parameters:

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 three 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 $prefix , string $uri )

Returns:

Returns TRUE on success or FALSE on failure.
