DOMDocument->registerNodeClass()

DOMDocument->registerNodeClass()

(no version information, might be only in CVS)

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.

Příklady

Příklad 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();

?>

Výše uvedený příklad vypíše:

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