note 65969 added to function.dom-domdocument-getelementsbytagname

(As of v5.0.5, Win32) Altering the document structure while iterating the NodeList returned by getElementsByTagName() affects the NodeList you are iterating. Combined with the DOMNode->insertBefore() method, this is a good way to create an infinite loop! Example: <?php $dom = new DOMDocument(); $rootNode = $dom->createElement('root'); $dom->appendChild($rootNode); $firstNode = $dom->createElement('first'); $rootNode->appendChild($firstNode); $allnodes = $dom->getElementsByTagName('*'); foreach ($allnodes as $node) { $newNode = $dom->createElement('infinite'); $node->parentNode->insertBefore($newNode, $node); } # the loop never terminates; on the next iteration, $node <= $newNode, another 'infinite' node is created and inserted before it, and so on ?> ---- Server IP: 66.163.161.117 Probable Submitter: 71.240.241.169 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.dom-domdocument-getelementsbytagname.php Edit -- http://master.php.net/note/edit/65969 Del: integrated -- http://master.php.net/note/delete/65969/integrated Del: useless -- http://master.php.net/note/delete/65969/useless Del: bad code -- http://master.php.net/note/delete/65969/bad+code Del: spam -- http://master.php.net/note/delete/65969/spam Del: non-english -- http://master.php.net/note/delete/65969/non-english Del: in docs -- http://master.php.net/note/delete/65969/in+docs Del: other reasons-- http://master.php.net/note/delete/65969 Reject -- http://master.php.net/note/reject/65969 Search -- http://master.php.net/manage/user-notes.php
