| The tostringlist documentation says "Returns a list of (optionally) encoded strings containing the XML data. It does not guarantee any specific sequence, except that "".join(tostringlist(element)) == tostring(element).". But in reality it is possible to get tostringlist to return a string and not a list. The following code will demonstrates problem, by failing with a TypeError: from xml.etree.ElementTree import Element, tostringlist, tostring element = Element("foo") print ("".join(tostringlist(element)) == tostring(element)) | ||

| Einar, TypeError is raised because tostring/tostringlist return bytes with the default encoding, and you can't join bytes on "" (which is unicode). | ||
