xml_set_element_handler — Set up start and end element handlers

### Descrierea

xml_set_element_handler ( resource `$parser` , callable `$start_element_handler` , callable `$end_element_handler` ) : bool

Sets the element handler functions for the XML `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`.

### Parametri

`parser`

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

`start_element_handler`

  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.

`end_element_handler`

  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.
