From: Operating system: All PHP version: Irrelevant Package: *XML functions Bug Type: Feature/Change Request Bug description:XPath processing-instruction() function is not supported.

' <bar><?baz href="ftw" ?></bar>' . "\n" . '</foo>'; $sxe = simplexml_load_string($xml); var_dump( $sxe->xpath('//bar') ); var_dump( $sxe->xpath('//processing-instruction(\'baz\')') ); Expected result: ---------------- //bar array(3) { [0]=> object(SimpleXMLElement)#2 (1) { [0]=> string(6) "Gordon" } [1]=> object(SimpleXMLElement)#3 (0) { } [2]=> object(SimpleXMLElement)#4 (1) { ["baz"]=> object(SimpleXMLElement)#5 (0) { } } } //processing-instruction('baz') array(1) { [2]=> object(SimpleXMLElement)#6 (1) { … } } Actual result: -------------- //bar array(3) { [0]=> object(SimpleXMLElement)#2 (1) { [0]=> string(6) "Gordon" } [1]=> object(SimpleXMLElement)#3 (0) { } [2]=> object(SimpleXMLElement)#4 (1) { ["baz"]=> object(SimpleXMLElement)#5 (0) { } } } //processing-instruction('baz') array(0) { } -- Edit bug report at http://bugs.php.net/bug.php?id=52751&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52751&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52751&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52751&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52751&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52751&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52751&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52751&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52751&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52751&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52751&r=support Expected behavior: http://bugs.php.net/fix.php?id=52751&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52751&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52751&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52751&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52751&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52751&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52751&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52751&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52751&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52751&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52751&r=mysqlcfg
