Summary: Extending DOM classes work only if copy of object
present
-Status: Open
+Status: Wont fix
Type: Bug
Package: DOM XML related
Operating System: Linux

New Comment:
The tree does not maintain object state. If you are only looking for
your own
classtypes to be returned by the DOM methods/properties then use
registerNodeClass() to register the types.

Description:
------------
Extending some DOM classes (f.e. DOMDOcument, DOMElement I think others,
but not
tested) work. But when such elemenmt appended to the document,
additional
information lost. Meantime, when copy of object saved alsewere, all work
as
expected.
First mention of this bug and initial workaround in comment
http://php.net/manual/tr/book.dom.php#80613 by ryoroxdahouse at hotmail
dot com.
I make automattical workaround like (
http://hinikato.blogspot.com/2009/10/domelement.html?
showComment=1270202266600#c284093039037001302 ):
class MyElement extends DOMElement
{
public function __construct($name, $value = null, $uri = null) {
parent::__construct($name, $value, $uri);
$GLOBALS['PHP_HACK_DOM_ELEMENT'][spl_object_hash($this)] = $this;
//Note,
reference is not enough :(
}
public function __destruct() {
unset($GLOBALS['PHP_HACK_DOM_ELEMENT'][spl_object_hash($this)]);
}
}
But as we need object copy, not just reference it requires double of
memmory!
Test script:
---------------
<?
class MyElement extends DOMElement{}
$doc = new DOMDocument();
$doc->appendChild(new MyElement('test'));
var_dump($doc->documentElement);
?>
Expected result:
----------------
object(MyElement)#4 (0) { }
Actual result:
--------------
object(DOMElement)#4 (0) { }
