#40762 [NEW]: xml_parser failed to parse mixed coding file

From: forward at hongyu dot org Operating system: Linux and Windows PHP version: 5.2.1 PHP Bug Type: *XML functions Bug description: xml_parser failed to parse mixed coding file Description: ------------ My RSS parser failed after I upgrade the PHP version on my server from 4.x to 5.2. When I debugged the code, I found the error was caused by the xml_parse() function's failure to parse the UTF-8 encoded RSS message, which is originally converted from a GB18030 string. The error message looks like: "Warning: xml_parse() [function.xml-parse]: input conversion failed due to input error, bytes 0x9B 0xE6 ..." The orginal GB encoded string consists of Chinese characters, but I converted it to UTF-8 coding using function iconv(). I can view the converted string correctly on web browsers, which means that there is no converting error. So the failure only comes from xml_parse() function, I believe. For your testing purpose, an example of the original GB18030 string can be downloaded at http://www.la-chinese.com/forum/rss.php?f=19 Thanks! Reproduce code: --------------- // variable $gb contains the GB encoded string, e.g., from // web address http://www.la-chinese.com/forum/rss.php?f=19 // variable $utf contains the UTF-8 string converted from // the original GB encoded string $urf = iconv('GB18030','UTF-8', $gb); // function feed_start_end and feed_end_element etc. are from // the package Magpierss http://magpierss.sourceforge.net/ xml_set_object( $parser, $this ); xml_set_element_handler($parser, 'feed_start_element', 'feed_end_element' ); xml_set_character_data_handler( $parser, 'feed_cdata' ); $status = xml_parse( $parser, $utf ); Expected result: ---------------- No error message. Actual result: -------------- Warning: xml_parse() [function.xml-parse]: input conversion failed due to input error, bytes 0x9B 0xE6 ... -- Edit bug report at http://bugs.php.net/?id=40762&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40762&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40762&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40762&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40762&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40762&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40762&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40762&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40762&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40762&r=support Expected behavior: http://bugs.php.net/fix.php?id=40762&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40762&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40762&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40762&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40762&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40762&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40762&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40762&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40762&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40762&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40762&r=mysqlcfg
