ID: 22192 User updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Wont fix Bug Type: XML related -Operating System: all +Operating System: Windows 2000 PHP Version: 4.3.0 New Comment:
Thanks for your quick reply. I asked for changing the default (which has some backwards compatibility issue) and for improving the documentation (which does not). Should I raise the documentation part as a separate bug report? As for the backwards compatibility issue, this does not mean that it cannot be changed. It just requires more careful planning, i.e. tell people now that they should not rely on the default in the future, and change it with the next major version (e.g. 5.0). In the long term, everybody will win. Previous Comments: ------------------------------------------------------------------------ [2003-02-12 18:32:46] [EMAIL PROTECTED] You can change it within your script with xml_parser_set_option(), as you most likely already know. But we can't change the default because of backwards compatibility. ------------------------------------------------------------------------ [2003-02-12 17:13:18] [EMAIL PROTECTED] changed 'OS' from 'Windows 2000' to 'all' ------------------------------------------------------------------------ [2003-02-12 17:04:33] [EMAIL PROTECTED] 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 this bug report at http://bugs.php.net/?id=22192&edit=1
