DOMDocument->registerNodeClass() -- Register extended class used to create base node type

Descrizione

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.

Elenco dei parametri

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.

Valori restituiti

Restituisce TRUE in caso di successo, FALSE in caso di fallimento.

Esempi

Esempio 1. 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();

?>

Il precedente esempio visualizzerà:

<?xml version="1.0"?>
<root><child foo="bar"/></root>
