Bug #64899 [Nab]: Elements with values of empty string are turned into void elements

Edit report at https://bugs.php.net/bug.php?id=64899&edit=1 ID: 64899 User updated by: douglas dot wright at pre-school dot org dot uk Reported by: douglas dot wright at pre-school dot org dot uk Summary: Elements with values of empty string are turned into void elements Status: Not a bug Type: Bug Package: DOM XML related Operating System: Windows 7 PHP Version: 5.5.0RC1 Block user comment: N Private report: N New Comment: Hi The workaround of inserting an empty text node manually after element creation still seems to work, but inserting a text node is what the $value param in createElement($name,$value) is surely for? i.e. $script = $doc->createElement ('script', '') //not working in 5.5 is the same thing as: $script = $doc->createElement ('script'); $script->appendChild ($doc->createTextNode ('')); //does work in 5.5 On setting, this creates a Text node with the unparsed contents of the string Previous Comments: ------------------------------------------------------------------------ [2013-05-22 15:06:47] ab@php.net The behaviour you describe is pretty valid for XML. saveHTML() method should be used if you need a HTML conform output. Also the behavior is different in 5.4 when using loadXML (tested with your snippet). PHP 5.5 uses libxml 2.9.1 where 5.4 uses libxml 2.7.8. libxml supports HTML 4.0 parser only AFAIR (yet at least). You might be also interested in workarounds suggested by users http://de2.php.net/manual/en/domdocument.savehtml.php ------------------------------------------------------------------------ [2013-05-22 11:41:55] douglas dot wright at pre-school dot org dot uk Description: ------------ There is a regression in PHP5.5RC where empty text nodes seem to be lost e.g. <script src=""></script> is turned into <script src=""/> This breaks XHTML pages because browsers don't recognise the self-closing syntax. In PHP 5.3 and 5.4 the two calls below had different output $doc->createElement('script') output <script/> $doc->createElement('script', '') output <script></script> In PHP5.5, they both output <script/> only. Documents parsed using loadXML suffer this too - <script></script> loses the inner text node and is transformed into <script/>. Test script: --------------- <?php error_reporting(E_ALL | E_STRICT); ini_set('display_errors', 1); $doc = new DOMDocument; $script = $doc->createElement('script', ''); $script->setAttribute('src', 'foo.js'); $doc->appendChild($script); echo $doc->saveXML(); $doc->loadXML('<script src="abc.js"></script>'); echo $doc->saveXML(); Expected result: ---------------- <?xml version="1.0"?> <script src="foo.js"></script> <?xml version="1.0"?> <script src="foo.js"></script> Actual result: -------------- <?xml version="1.0"?> <script src="foo.js"/> <?xml version="1.0"?> <script src="foo.js"/> ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64899&edit=1
