Bug #74989 [NEW]: DOMElement::setAttribute() should report error when @xml:space = 'foo'

From: paul at sparrowhawkcomputing dot com Operating system: Windows 10 Pro PHP version: 5.6.31 Package: DOM XML related Bug Type: Bug Bug description:DOMElement::setAttribute() should report error when @xml:space = 'foo' Description: ------------ To conform to the XML spec, DOMElement::setAttributeNS() [and other related methods like DOMDocument::createAttributeNS(), etc] incorrectly allows @xml:space='foo'. See the related bug (https://bugs.php.net/bug.php?id=74988) for the details on WHY this should not be allowed. Test script: --------------- libxml_use_internal_errors( true ); libxml_clear_errors(); $dom = new DOMDocument(); $root = $dom->createElement( 'root' ); $root->setAttributeNS( 'http://www.w3.org/XML/1998/namespace', 'xml:space', 'foo' ); $errs = libxml_get_errors(); $dom->appendChild( $root ); $xml = $dom->saveXML(); var_dump( $errs ); var_dump( $xml ); Expected result: ---------------- Either: DOMElement::setAttributeNS() [and other related methods like DOMDocument::createAttributeNS(), etc) should return false and libxml_get_errors() should report the well-formedness error or DOMElement::setAttributeBS() should return true but just ignore setting the attribute and it's value. Actual result: -------------- array(0) { } string(46) "<?xml version="1.0"?> <root xml:space="foo"/> " -- Edit bug report at https://bugs.php.net/bug.php?id=74989&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=74989&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=74989&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=74989&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=74989&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=74989&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=74989&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=74989&r=needscript Try newer version: https://bugs.php.net/fix.php?id=74989&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=74989&r=support Expected behavior: https://bugs.php.net/fix.php?id=74989&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=74989&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=74989&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=74989&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=74989&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=74989&r=dst IIS Stability: https://bugs.php.net/fix.php?id=74989&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=74989&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=74989&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=74989&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=74989&r=mysqlcfg
