#40906 [NEW]: meta tag automagically appears in XHTML documents

From: php at phihag dot de Operating system: independent PHP version: 5.2.1 PHP Bug Type: DOM XML related Bug description: meta tag automagically appears in XHTML documents Description: ------------ When creating a <head> tag inside a XHTML document which is designated as that by a specified doctype, a strange tag is inserted automatically. I suppose this is because http://www.w3.org/TR/xslt#section-HTML-Output-Method specifies this for HTML output. However, this tag is even wrong in this XHTML case because it states "Content-Type: text/html" instead of the right "Content-Type: application/xhtml+xml". Reproduce code: --------------- <?php $doc = new DOMDOcument(); $doc->loadXML('<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">' . '<html xmlns="http://www.w3.org/1999/xhtml" />'); $head = $doc->documentElement->appendChild($doc->createElement("head")); echo $doc->saveXML(); ?> Expected result: ---------------- <?xml version="1.0"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head /> </html> Actual result: -------------- <?xml version="1.0"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> </head></html> -- Edit bug report at http://bugs.php.net/?id=40906&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40906&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40906&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40906&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40906&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40906&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40906&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40906&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40906&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40906&r=support Expected behavior: http://bugs.php.net/fix.php?id=40906&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40906&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40906&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40906&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40906&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40906&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40906&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40906&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40906&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40906&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40906&r=mysqlcfg
