xml_set_element_handler — Set up start and end element handlers

Description

xml_set_element_handler(XMLParser $parser, callable $start_handler, callable $end_handler): bool

Sets the element handler functions for the XML parser. start_handler and end_handler are strings containing the names of functions that must exist when xml_parse() is called for parser.

Parameters

parser

A reference to the XML parser to set up start and end element handler functions.

start_handler

The function named by start_handler must accept three parameters:

start_element_handler(XMLParser $parser, string $name, array $attribs)

parser: The first parameter, parser, is a reference to the XML parser calling the handler.
name: The second parameter, name, contains the name of the element for which this handler is called.If case-folding is in effect for this parser, the element name will be in uppercase letters.
attribs: The third parameter, attribs, contains an associative array with the element's attributes (if any).The keys of this array are the attribute names, the values are the attribute values.Attribute names are case-folded on the same criteria as element names.Attribute values are not case-folded. The original order of the attributes can be retrieved by walking through attribs the normal way, using each().The first key in the array was the first attribute, and so on.

Note: Instead of a function name, an array containing an object reference and a method name can also be supplied.

end_handler

The function named by end_handler must accept two parameters:

end_element_handler(XMLParser $parser, string $name)

parser: The first parameter, parser, is a reference to the XML parser calling the handler.
name: The second parameter, name, contains the name of the element for which this handler is called.If case-folding is in effect for this parser, the element name will be in uppercase letters.
