xml_set_object — Use XML Parser within an object
$parser
, object &$object
)
This function allows to use parser
inside
object
. All callback functions could be set with
xml_set_element_handler() etc and assumed to be
methods of object
.
In addition to calling xml_parser_free() when the parsing
is finished, as of PHP 7.0.0 it is necessary to also explicitly unset the
reference to parser
to avoid memory leaks.
parser
A reference to the XML parser to use inside the object.
object
The object where to use the XML parser.
Gibt bei Erfolg TRUE
zurück. Im Fehlerfall wird FALSE
zurückgegeben.
Beispiel #1 xml_set_object() example
<?php
class XMLParser
{
private $parser;
function __construct()
{
$this->parser = xml_parser_create();
xml_set_object($this->parser, $this);
xml_set_element_handler($this->parser, "tag_open", "tag_close");
xml_set_character_data_handler($this->parser, "cdata");
}
function __destruct()
{
xml_parser_free($this->parser);
unset($this->parser);
}
function parse($data)
{
xml_parse($this->parser, $data);
}
function tag_open($parser, $tag, $attributes)
{
var_dump($tag, $attributes);
}
function cdata($parser, $cdata)
{
var_dump($cdata);
}
function tag_close($parser, $tag)
{
var_dump($tag);
}
}
$xml_parser = new XMLParser();
$xml_parser->parse("<A ID='hallo'>PHP</A>");
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
string(1) "A" array(1) { ["ID"]=> string(5) "hallo" } string(3) "PHP" string(1) "A"
