Enable using xml:lang with normal interfaces.
Using the special language value '*' will return a dictionary of all such elements keyed by language. >>> msg = Message() >>> msg['body'] = 'Hi!' >>> msg['body|sv'] = 'Hej!' >>> print(msg) '<message xmlns="jabber:client"> <body>Hi!</body> <body xml:lang="sv">Hej!</body> </message>' >>> print(msg['body|*']) OrderedDict( ('', 'Hi!'), ('sv', 'Hej!')) Remaining items: - Stanza path matching does not support language specifiers for normal interfaces, only for plugins.
