# xml_set_element_handler

(PHP 3>= 3.0.6, PHP 4 )

xml_set_element_handler -- set up start and end element handlers

## Description

bool xml_set_element_handler ( resource parser, string start_element_handler, string end_element_handler)

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

The function named by `start_element_handler` must accept three parameters: `start_element_handler` ( resource 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.

The function named by `end_element_handler` must accept two parameters: `end_element_handler` ( resource 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.

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

`TRUE` is returned if the handlers are set up, `FALSE` if `parser` is not a parser.

> Anmerkung: Anstelle eines Funktionsnamens kann auch ein Array mit einer Objekt-Referenz und dem Namen einer Methode angegeben werden.
