#46143 [NEW]: Serializing SimpleXML removes the root node; asXML on unserailized breaks

From: firehed at gmail dot com Operating system: OS X 10.5 PHP version: 5.2.6 PHP Bug Type: SimpleXML related Bug description: Serializing SimpleXML removes the root node; asXML on unserailized breaks Description: ------------ If you serialize a SimpleXMLElement object, the root-level node is lost, causing the unserialize() event to issue a warning-level error (and creating an empty SimpleXMLElement object) and cause most other SimpleXMLElement methods to fail with a warning-level error. Reproduce code: --------------- <?php $xml = new SimpleXMLElement('<test><foo>1</foo><bar>2</bar></test>'); $serialized = serialize($xml); $unserialized = unserialize($serialized); $unserialized->addChild('testing', 'worked'); echo $unserialized->asXML(); Expected result: ---------------- <?xml version="1.0"?> <test><foo>1</foo><bar>2</bar><testing>worked</testing></test> Actual result: -------------- Warning: unserialize() [function.unserialize]: Node no longer exists in /Applications/MAMP/htdocs/serialxml.php on line 4 Warning: SimpleXMLElement::addChild() [function.SimpleXMLElement-addChild]: Node no longer exists in /Applications/MAMP/htdocs/serialxml.php on line 5 Warning: SimpleXMLElement::addChild() [function.SimpleXMLElement-addChild]: Cannot add child.
