String building XML is *always* dicey and it is *VERY* easy to introduce encoding problems. Something at least with an codepage codec would be good. [although it *should* work, I manipulate WebDAV servers via curl CLI all the time]. In Python a combination of ElementFlow and the codecs module is perfection. I assume there is a PHP equivalent. -- Adam Tauno Williams <awilliam@whitemice.org>
