From: kenashkov at gmail dot com Operating system: Fedora Core 4 PHP version: 5.2.3 PHP Bug Type: SimpleXML related Bug description: Xpath evaluation in SimpleXMLElement
Description: ------------ The evaluation of the Xpath expressions is not relative to the node against which they are called ([2]). Worse - even after cloning a node from the structure and evaluating the xpath, the xpath expression seems to be evaluated against the original structure, not against the new one (which is a copy of a part of the original) ([3]). This was discussed in the dev-list here: http://marc.info/?l=php-dev&m=118001203709813&w=2 If this is not a bug, but expected result, I think a note addressing this behaviour must be added in the docs. Reproduce code: --------------- $str = '<rootnode><level1_node1><level2_node1></level2_node1></level1_node1><level1_node2></level1_node2></rootnode>'; $x = new SimpleXMLElement($str); //[1] $r1 = $x->xpath('/*'); print $r1[0]->getName().' '; //[2] $r2 = $x->level1_node1[0]->xpath('/*'); print $r2[0]->getName().' '; //[3] $z = clone $x->level1_node1[0]; $r3 = $z->xpath('/*'); print $r3[0]->getName().' '; Expected result: ---------------- rootnode level1_node1 level1_node1 Actual result: -------------- rootnode rootnode rootnode -- Edit bug report at http://bugs.php.net/?id=41663&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41663&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41663&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41663&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41663&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41663&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41663&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41663&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41663&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41663&r=support Expected behavior: http://bugs.php.net/fix.php?id=41663&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41663&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41663&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41663&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41663&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41663&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41663&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41663&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41663&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41663&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41663&r=mysqlcfg
