note 91567 added to function.simplexml-element-xpath

Whether it returns a false or empty array for a non-existing path seems to depend on libxml version. I tried the following code: <?php $data = '<foo><bar></bar></foo>'; $xml = simplexml_load_string($data); print gettype($xml->xpath('/first/second')); ?> On a machine with libxml 2.6.16 and PHP 5.2.8 I got back boolean. On a different machine with libxml 2.7.3 and PHP 5.2.8/5.2.9 I got back empty array. You can check the libxml version from command line by executing: php --ri libxml or simply look at phpinfo() output ---- Server IP: 64.71.164.2 Probable Submitter: 194.126.108.2 ---- Manual Page -- http://www.php.net/manual/en/function.simplexml-element-xpath.php Edit -- https://master.php.net/note/edit/91567 Del: integrated -- https://master.php.net/note/delete/91567/integrated Del: useless -- https://master.php.net/note/delete/91567/useless Del: bad code -- https://master.php.net/note/delete/91567/bad+code Del: spam -- https://master.php.net/note/delete/91567/spam Del: non-english -- https://master.php.net/note/delete/91567/non-english Del: in docs -- https://master.php.net/note/delete/91567/in+docs Del: other reasons-- https://master.php.net/note/delete/91567 Reject -- https://master.php.net/note/reject/91567 Search -- https://master.php.net/manage/user-notes.php
