Hi,
i think, you identified the problem correctly in the previous mail:
>> Before I created it as a generator I was able to use iter on my lxml root objects, now I cannot iter.

It is not clear, what the previous - working - version was, but there
is a difference between using built-in iteration handling (with
built-in iter(...) or implicitly via "for elem in
some_iterable_object: ...") and with the specialised "iter" method of
root in the lxml library (which has specific functionalities).
I don't have much experience with that library, but if your change was
basically adding a "generator" layer around "roots",
you may try to iterate over it to get its elements, which might
supposedly support the method, you were using previously.
e.g. (completely untested, as there is no xml underlying given in your sample)
for root in roots:
    for meet in root.iter("meeting"):
        ...

hth,
