From: [EMAIL PROTECTED] Operating system: Windows 2000 PHP version: 4.3.0 PHP Bug Type: XML related Bug description: casefolding option should be off by default
The default setting for casefolding for element and attribute names for standard PHP XML parsers (created with xml_parser_create()) is set to ON (see http://www.php.net/manual/en/ref.xml.php#xml.case-folding). Unfortunately, this is in strong contrast with the XML Standard, which specifies that all element and attribute names are case-sensitive (i.e. <foo> and <FOO> are two completely different things). Having to call xml_parser_set_option ($xml_parser, XML_OPTION_CASE_FOLDING, FALSE); every time is tedious. Forgetting it results in faulty code (even if it may look like it works). This is very much against the quick and straightforward way that programmers have come to love and expect of PHP. The default for case-folding should therefore be changed, so that it is off. Even better would be to completely disable this option in the PHP glue interfacing with expat. Case-folding of element and attribute names and XML simply don't belong together. Changing defaults may not be done easily, so planning for this should start as early as possible. As a first step, it would also be very helpful to improve the documentation. The documentation should very clearly say that using xml_parser_set_option() after xml_parser_create() is necessary, and in all examples, xml_parser_set_option() should actually be called. Many thanks in advance for fixing this problem, and helping with correct XML and easy PHP programming. Please contact me if you need more information or have questions. Regards, Martin. Some additional remarks: The option is either a remnant of SGML (the precursor of XML), or remained from the time where "to case-fold or not to case-fold" was still under consideration before XML got finalized (more than 5 years ago). Fortunately, the parser marks "<foo>this is some text</FOO>" as illegal even if case-folding is set on, so the case-folding option only affects values passed to the callbacks. But that's bad enough. -- Edit bug report at http://bugs.php.net/?id=22192&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=22192&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=22192&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=22192&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=22192&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=22192&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=22192&r=support Expected behavior: http://bugs.php.net/fix.php?id=22192&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=22192&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=22192&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=22192&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=22192&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=22192&r=dst IIS Stability: http://bugs.php.net/fix.php?id=22192&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=22192&r=gnused
