Leonid,
Thanks for this patch.
However, give me time to work with this a bit. The reason that the
mappedName, which you changed, is used is to prevent conflicts with
element names that are the same as Python keywords. For example, we
could generate code like this:
elif nodeName_ == 'with':
obj_ = boosterType.factory()
obj_.build(child_)
self.with = obj_
obj_.original_tagname_ = 'with'
instead of this:
elif nodeName_ == 'with':
obj_ = boosterType.factory()
obj_.build(child_)
self.with_ = obj_
obj_.original_tagname_ = 'with'
Because "with" is a Python keyword, "self.with" produces an error.
I had forgotten about this, but one of my tests revealed it.
So, I'll investigate to see if I can adapt your fix so that it works
with both your test and mine.
Thanks for providing that test case. It will make my work easier.
More later.
