#42259 [NEW]: SimpleXMLIterator loses ancestry

From: jazzslider at gmail dot com Operating system: Windows PHP version: 5.2.4RC1 PHP Bug Type: SPL related Bug description: SimpleXMLIterator loses ancestry Description: ------------ I'm getting this error on PHP 5.2.2 and haven't had a chance to upgrade to 5.2.4 yet, but I wanted to mention it anyway since it seems like it would be sort of a niche bug. When iterating over XML using RecursiveIteratorIterator(SimpleXMLIterator(xml)), XPath expressions intended to retrieve a node's ancestors do not retrieve all of them. In the below example, this means that only the immediate parent of the current node can be identified; in other test cases I've run, not even the parent was available. Reproduce code: --------------- $xml = '<xml><fieldset1><field1/><field2/></fieldset1><fieldset2><options><option1/><option2/><option3/></options><field1/><field2/></fieldset2></xml>'; $sxe = new SimpleXMLIterator($xml); $rit = new RecursiveIteratorIterator($sxe, RecursiveIteratorIterator::LEAVES_ONLY); foreach ($rit as $child) { $path = ''; $ancestry = $child->xpath('ancestor-or-self::*'); foreach ($ancestry as $ancestor) { $path .= $ancestor->getName() . '/'; } $path = substr($path, 0, strlen($path) - 1); echo count($ancestry) . ' steps: ' . $path . PHP_EOL; } Expected result: ---------------- 3 steps: xml/fieldset1/field1 3 steps: xml/fieldset1/field2 1 steps: xml/fieldset2/options/option1 1 steps: xml/fieldset2/options/option2 1 steps: xml/fieldset2/options/option3 3 steps: xml/fieldset2/field1 3 steps: xml/fieldset2/field2 Actual result: -------------- 2 steps: fieldset1/field1 2 steps: fieldset1/field2 2 steps: options/option1 2 steps: options/option2 2 steps: options/option3 2 steps: fieldset2/field1 2 steps: fieldset2/field2 -- Edit bug report at http://bugs.php.net/?id=42259&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42259&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42259&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42259&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42259&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42259&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42259&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42259&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42259&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42259&r=support Expected behavior: http://bugs.php.net/fix.php?id=42259&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42259&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42259&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42259&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42259&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42259&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42259&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42259&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42259&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42259&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42259&r=mysqlcfg
