note 66467 added to ref.simplexml

There is some serious weirdness in the way PHP 5.1.4 is handling non-existent children in the XML tree. <?php $xmlstr = "<html><body/></html>"; $xml = simplexml_load_string($xmlstr); var_dump($xml->body); // Empty node => empty SimpleXMLElement var_dump($xml->head); // Nonexistent node => empty SimpleXMLElement var_dump($xml->head->title); // Child of nonexistent node => NULL (!) var_dump($xml->head->title->foo); // NULL + Notice: Trying to get property of non-object var_dump(count($xml)); // int(1) var_dump(count($xml->head)); // int(0) var_dump(count($xml->body)); // int(1) !! - see below foreach($xml as $child) { var_dump(count($child)); // int(0) for <body/> now!! } ?> Be aware of these behaviors if you're trying to run clean under E_ALL. ---- Server IP: 64.71.164.2 Probable Submitter: 69.205.153.76 ---- X-Spam-Status: No, hits=3.3 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER, HTML_MESSAGE autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/ref.simplexml.php Edit -- http://master.php.net/note/edit/66467 Del: integrated -- http://master.php.net/note/delete/66467/integrated Del: useless -- http://master.php.net/note/delete/66467/useless Del: bad code -- http://master.php.net/note/delete/66467/bad+code Del: spam -- http://master.php.net/note/delete/66467/spam Del: non-english -- http://master.php.net/note/delete/66467/non-english Del: in docs -- http://master.php.net/note/delete/66467/in+docs Del: other reasons-- http://master.php.net/note/delete/66467 Reject -- http://master.php.net/note/reject/66467 Search -- http://master.php.net/manage/user-notes.php
