"continue" outside the loop?
imho the old one is better. Don't use "continue" outside the loop.
This comment is applicable for the all places in this patch.

Better to keep the old one, since it is easy to maintain.
Example:
Maybe in feature if we want to use different formats, we can simply
update at single place.
