Bug #77686 [NEW]: Removed elements are still returned by getElementById

From: gtisza at gmail dot com Operating system: PHP version: 7.3.2 Package: DOM XML related Bug Type: Bug Bug description:Removed elements are still returned by getElementById Description: ------------ Removing a DOMElement from a HTML document does not refresh the id index; getElementById() will still return the removed element. (getElementsByTagName(), in contrast, works as expected.) Live test: https://3v4l.org/UQYTG Calling setIdAttribute() on the removed element apparently updates the index and fixes getElementById() behavior. It does not fix it for any children of the removed node, however. Test script: --------------- $doc = new DOMDocument; $doc->loadHTML('<html><body id="x"><div id="y"></div></body></html>'); $body = $doc->getElementById('x'); $div = $doc->getElementById('y'); $doc->getElementById('y'); // <div id="y"> -- Edit bug report at https://bugs.php.net/bug.php?id=77686&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=77686&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=77686&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=77686&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=77686&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=77686&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=77686&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=77686&r=needscript Try newer version: https://bugs.php.net/fix.php?id=77686&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=77686&r=support Expected behavior: https://bugs.php.net/fix.php?id=77686&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=77686&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=77686&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=77686&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=77686&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=77686&r=dst IIS Stability: https://bugs.php.net/fix.php?id=77686&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=77686&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=77686&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=77686&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=77686&r=mysqlcfg
