Bug #55531 [NEW]: Vertical tabs ignored by XMLWriter

From: brianlmoon Operating system: Linux PHP version: 5.3.8 Package: XML related Bug Type: Bug Bug description:Vertical tabs ignored by XMLWriter Description: ------------ When text contains vertical tabs, XMLWriter silently ignores them and generates invalid XML. This is not an issue where the text is invalid UTF-8. It is valid UTF-8 data. Vertical tabs are simply not allowed in XML by rule. I would expect XMLWriter to encode it as it would any other character not allowed in XML. I suspect that Test script: --------------- <?php $xml = new XmlWriter(); $xml->openMemory(); $xml->startDocument('1.0', 'UTF-8'); $xml->writeElement("test", "This data contains a \vvertical tab"); $xml->endElement(); $data = $xml->outputMemory(true); $sxml = simplexml_load_string($data); ?> Expected result: ---------------- Either an error or valid XML. Actual result: -------------- Invalid XML is silently created. For example, SimpleXML::addchild() throws a warning: SimpleXMLElement::asXML(): xmlEscapeEntities : char out of range when a vertical tab is present and the node is not added. -- Edit bug report at https://bugs.php.net/bug.php?id=55531&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55531&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55531&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55531&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55531&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55531&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55531&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55531&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55531&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55531&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55531&r=support Expected behavior: https://bugs.php.net/fix.php?id=55531&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55531&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55531&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55531&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55531&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55531&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55531&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55531&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55531&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55531&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55531&r=mysqlcfg
