I would think that the intended output would be:

Factory A produces 3 widgets;
Factory B produces 5 widgets and 1 gadget;
Factory C produces 3 gadgets;
Factory D produces 1 gadget and 1 excess product - whatever that is;
Factory E and beyond produce excess products.

So, you are really trying to keep track of 2 changing numbers,...the number of current product still required, as well as the capacity of the factory.  When the number of the current product required gets to zero, you change products - gotta figure out how to prioritize those.  When the capacity of the current factory gets to zero (has been fully allocated), you change factories - which would be controlled by the order of the input xml, I assume.

So, is it better to do this incrementally - subtract one from required and one from remaining capacity,...or to do bulk comparisons - I need to build 8, but can only build 3, so give all three to Factory 1, and subtract 3 from WidgetRequirement, then I still need to build 5, but Factory B can build 6, so subtract all 5 from the WidgetRequirement and the CurrentCapacity and then figure out what to do with the remaining CurrentCapacity for Factory B.
