    It doesn't work for me, even with simple cases:

    >>> dict2xml({'hello': 1})
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 3, in dict2xml
KeyError: 'int'

    Using exec has really many problems (security, speed, ...) and it's not required here at all.
