note 69638 added to function.simplexml-element-xpath

I was looking to find all of a given element type with attributes which were not of a particular value (including null items). I tried this... <?php $xml->xpath("//pg[@show!='none']"); ?> ...But that only worked if there was in fact some attribute. I thought this should work (shouldn't it?), but it didn't: <?php $xml->xpath("//pg[@show!='none' or !@show]"); ?> The solution is to use the not() function: <?php $xml->xpath("//pg[not(@show='none')]"); ?> ---- Server IP: 66.163.161.117 Probable Submitter: 218.17.96.1 ---- Manual Page -- http://www.php.net/manual/en/function.simplexml-element-xpath.php Edit -- https://master.php.net/note/edit/69638 Del: integrated -- https://master.php.net/note/delete/69638/integrated Del: useless -- https://master.php.net/note/delete/69638/useless Del: bad code -- https://master.php.net/note/delete/69638/bad+code Del: spam -- https://master.php.net/note/delete/69638/spam Del: non-english -- https://master.php.net/note/delete/69638/non-english Del: in docs -- https://master.php.net/note/delete/69638/in+docs Del: other reasons-- https://master.php.net/note/delete/69638 Reject -- https://master.php.net/note/reject/69638 Search -- https://master.php.net/manage/user-notes.php
