&reftitle.parameters;

&xml.parser.param;

`start_handler`

- &xml.handler.description;

  The signature of the handler must be: `void```start_element_handler`` `XMLParser` `parser` `string` `name` `array` `attributes`

  &xml.handler.parser.param;

  `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.

`attributes`

- An associative array with the element's attributes. The array is empty if the element has no attributes. 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 order in which `attributes` is traversed is identical to the order in which the attributes were declared.

`end_handler`

- &xml.handler.description;

  The signature of the handler must be: `void```end_element_handler`` `XMLParser` `parser` `string` `name`

  &xml.handler.parser.param;

  `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.
