DOMDocument->registerNodeClass() — Register extended class used to create base node type
Popis
class DOMDocument {bool registerNodeClass ( string $baseclass, string $extendedclass )
}
This method allows you to register your own extended DOM class to be used afterward by the PHP DOM extension.
This method is not part of the DOM standard.
Seznam parametrů
- baseclass
The DOM class that you want to extend. You can find a list of these classes in the chapter introduction.
Of course, you won't be able to register a class extending DOMDocument but you can always start your document by instanciating your own extending class.
- extendedclass
Your extended class name. If NULL is provided, any previously registered class extending baseclass will be removed.
Návratové hodnoty
Vrací TRUE při úspěchu, FALSE při selhání.

Příklad 398. Adding a new method to DOMElement to ease our code
<?php
class myElement extends DOMElement {
function appendElement($name) {
return $this->appendChild(new myElement($name));
}
}
class myDocument extends DOMDocument {
function setRoot($name) {
return $this->appendChild(new myElement($name));
}
}
$doc = new myDocument();
$doc->registerNodeClass('DOMElement', 'myElement');
// From now on, adding an element to another costs only one method call !
$root = $doc->setRoot('root');
$child = $root->appendElement('child');
$child->setAttribute('foo', 'bar');
echo $doc->saveXML();
?>
Výše uvedený příklad vypíše:
<>< foo="bar"/></>
