#40105 [Bgs->Opn]: DOMDocument->createElement() unescapes numeric character references in values

ID: 40105 User updated by: fletch at pobox dot com Reported By: fletch at pobox dot com -Status: Bogus +Status: Open Bug Type: DOM XML related Operating System: linux PHP Version: 5.2.0 New Comment: Thanks for the quick response. I did change the bug status back to "open" but I didn't assign it, tony2001@php.net did. I believe you're right that this particular example both XML strings are the same, but only because the NCR I used represents a printable character. A non-printable character must be represented as its NCR. There's no way to craft a node whose value contains an NCR, and as such, no way to create an element whose value contains non-printable characters. Previous Comments: ------------------------------------------------------------------------ [2007-01-18 11:05:19] chregu@php.net <root>&#0160;</root> and <root> </root> (the space here being a non breakable space) is the same in the XML context... It doesn't matter, if your write a character as numerical entity or with the actual char. It's the same. You have to live with that. And please don't just assign bugs... ------------------------------------------------------------------------ [2007-01-18 06:01:08] fletch at pobox dot com I'm aware of the differences in escaping between createElement() and createTextNode() and neither one does what I describe. createElement() unescapes NCRs (as I described in the original description) while createTextNode() escapes values. In a nutshell, using createElement() I end up with "<root> </root>", and using createTextNode() I end up with "<root>&amp;#0160;</root>". There is no way to generate the literal XML "<root>&#0160;</root>" using either createElement() OR createTextNode() ------------------------------------------------------------------------ [2007-01-12 07:44:43] chregu@php.net It was decided to leave it as it is (for backwards compatibility reasons) use $dom->createTextNode() for the behaviour you want. ------------------------------------------------------------------------ [2007-01-11 23:28:30] fletch at pobox dot com There's a trivial error in the expected result text: the string length produced by var_dump() should be 65, not 59. ------------------------------------------------------------------------ [2007-01-11 23:26:27] fletch at pobox dot com Description: ------------ DOMDocument->createElement() unescapes any numeric character references (NCRs) contained in the value passed to its optional second parameter. It should preserve the value as passed. Reproduce code: --------------- <?php $dom = new DOMDocument( "1.0", 'UTF-8' ); $dom->appendChild( $dom->createElement( 'root', '&amp;&#0160;' ) ); var_dump( trim( $dom->saveXML() ) ); ?> Expected result: ---------------- string(59) "<?xml version="1.0" encoding="UTF-8"?> <root>&amp;&#0160;</root>" Actual result: -------------- string(59) "<?xml version="1.0" encoding="UTF-8"?> <root>&amp; </root>" ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=40105&edit=1
