Parâmetros

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.

Nota: Ao invés de um nome de função, um array contendo uma referência de objeto e ao nome de método também podem ser fornecidos.

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.
