Correctly, this should read: "attrib" is an attribute of "ETree" nodes (!)
(providing a mapping like access to the nodes attributes).

It is *NOT* an attribute of string (!) objects.

You have converted the tree root into a string (using "etree.tostring")
and then iterated over the resulting string. On those characters
you access "attrib" - which will not work as you expect.
