# xml_set_element_handler

xml_set_element_handler -- set up start and end element handlers

## Description

`int xml_set_element_handler` (int parser, string startElementHandler , string endElementHandler );

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

The function named by `startElementHandler` must accept three parameters:

``startElementHandler``(int parser, string name, string 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 `endElementHandler` must accept two parameters:

``endElementHandler``(int 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.

There is currently no support for object/method handlers.
