From: joey dot sabey at gmx dot com Operating system: linux PHP version: 7.3.9 Package: DOM XML related Bug Type: Bug Bug description:Invalid tags in DOM prevent attribute manipulation of siblings Description: ------------ --- From manual page: https://php.net/intro.dom --- When loading 'dirty' input that contains invalid tags (e.g. <foo>qwerty</foo>) with DOMDocument::loadHTML() it becomes impossible to manipulate the attributes of siblings of the invalid tag. Test script: --------------- <?php $works = <<<'HTML' <html> <body> <p><a href="http://example.com" id="thelink" class="alink">link</a></p> </body> </html> HTML; $broken = <<<'HTML' <html> <body> <p><foo>qwerty</foo><a href="http://example.com" id="thelink" class="alink">link</a></p> </body> </html> HTML; $dom = new DOMDocument(); $dom->loadHTML($works); $attr = $dom->getElementsByTagName('p')[0]->childNodes->item(0)->attributes; print_r($attr); $dom = new DOMDocument(); $dom->loadHTML($broken); $attr = $dom->getElementsByTagName('p')[0]->childNodes->item(0)->attributes; print_r($attr); ?> Expected result: ---------------- length of DOMNamedNodeMap is 3 in both Actual result: -------------- length of DOMNamedNodeMap is 3 (correct number of attributes) when there is no invalid tags in the parent tag, but is 0 when an invalid tag is a sibling -- Edit bug report at https://bugs.php.net/bug.php?id=78500&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=78500&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=78500&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=78500&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=78500&r=needscript Try newer version: https://bugs.php.net/fix.php?id=78500&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=78500&r=support Expected behavior: https://bugs.php.net/fix.php?id=78500&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=78500&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=78500&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=78500&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=78500&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=78500&r=dst IIS Stability: https://bugs.php.net/fix.php?id=78500&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=78500&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=78500&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=78500&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=78500&r=mysqlcfg
