Bug #70029 [Opn->Ver]: nodeValue of DOMElement list content of children nodes

Edit report at https://bugs.php.net/bug.php?id=70029&edit=1 ID: 70029 Updated by: cmb@php.net Reported by: Laurent dot Lyaudet at gmail dot com Summary: nodeValue of DOMElement list content of children nodes -Status: Open +Status: Verified Type: Bug Package: DOM XML related Operating System: Debian Linux PHP Version: 5.4.42 Block user comment: N Private report: N New Comment: Confirmed: <http://3v4l.org/nrYAR>. According to the "Document Object Model Core" specification[1] nodeValue is supposed to yield null for Element nodes, so the behavior may be considered as bug. However, it works this way since the beginnings of the DOM extension, and the documentation[2] isn't particularly clear with regard to the exact behavior, so changing the behavior would introduce a BC break which is not easily noticed. Nonetheless, this should be fixed for PHP 7 (even though beta1 has already been tagged, which marks the feature freeze), in my opinion.
