Fundamentally, an XML document is a sequence of Unicode characters, independent of any encoding. Therefore, when a the contents of a document or DTD are being read, it is often very convenient for APIs to use Python's unicode type as a means of reporting what is in the document. That's why the unicode objects exist for you. (Although, I would not count on xmlproc to be consistent about returning unicode). As for why you see them printed as u'...', that's because you are "print"-ing tuples and lists that contain unicode objects. If you instead print the unicode objects individually, rather than their containers, then the unicode strings will be encoded for you automatically to whatever Python thinks your screen can handle. >>> print [u'hello world', u'greetings'] [u'hello world', u'greetings'] >>> print u'hello world' hello world _______________________________________________ XML-SIG maillist - XML-SIG@python.org http://mail.python.org/mailman/listinfo/xml-sig
