If dataId is a string this won't work.

You have to forget about files when you're working with ZODB, because
this Database doesn't have any file in it. Those are all objects and
when you do something like
myobj = getattr(self, 'name')
you'll get an object. This object might be an instance of the File class
and thus behave like a file, but it still is only an object. Your
StringIO constructor already get the content of this object, i.e. the
text that is stored in it, because you give it via myobj.data.
The next thing is, if you already can access the text content via
myobj.data you don't need StringIO.

Suppose dataID contains the id of the object something like this:
obj = getattr(self, dataID)
for line in str(obj.data).split('\n'):
You will gain money by an immoral action.
