Here is an example of an easy mapping between xml and classes defined by user. <?php class XmlClass extends SimpleXMLElement { /** * Returns this object as an instance of the given class. */ public function asInstanceOf($class_name) { // should check that class_name is valid return simplexml_import_dom(dom_import_simplexml($this), $class_name); } public function __call($name, array $arguments) { echo "magic __call called for method $name on instance of ".get_class()."\n"; // class could be mapped according $this->getName() $class_name = 'Test'; $instance = $this->asInstanceOf($class_name); return call_user_func_array(array($instance, $name), $arguments); } } class Test extends XmlClass { public function setValue($string) { $this->{0} = $string; } } $xml = new XmlClass('<example><test/></example>'); $test = $xml->test->asInstanceOf('Test'); echo get_class($xml->test), "\n"; echo get_class($test), "\n"; $test->setValue('value set directly by instance of Test'); echo (string)$xml->test, "\n"; echo (string)$test, "\n"; $xml->test->setValue('value set by instance of XmlClass and magic __call'); echo (string)$xml->test, "\n"; echo (string)$test, "\n"; ?> XmlClass Test value set directly by instance of Test value set directly by instance of Test magic __call called for method setValue on instance of XmlClass value set by instance of XmlClass and magic __call value set by instance of XmlClass and magic __call ---- Server IP: 69.147.83.197 Probable Submitter: 90.17.219.181 ---- Manual Page -- http://www.php.net/manual/en/book.simplexml.php Edit -- https://master.php.net/note/edit/109154 Del: integrated -- https://master.php.net/note/delete/109154/integrated Del: useless -- https://master.php.net/note/delete/109154/useless Del: bad code -- https://master.php.net/note/delete/109154/bad+code Del: spam -- https://master.php.net/note/delete/109154/spam Del: non-english -- https://master.php.net/note/delete/109154/non-english Del: in docs -- https://master.php.net/note/delete/109154/in+docs Del: other reasons-- https://master.php.net/note/delete/109154 Reject -- https://master.php.net/note/reject/109154 Search -- https://master.php.net/manage/user-notes.php
