Sub Categories in my feed [fixed]

I have a modifed feed (Any Feed) in order to put items into another shop.

Problem at the moment is the feed is not displaying sub-categories, only parent categories. How in the world can I get it to display 1 sub-category and the parent? I'm bad at PHP.

What I'm looking for ie "Geek & Hobby -> Gundam Model Kit"

My feed: http://digitalsushi.co.za/index.php?route=feed/any_feed

My feed is a bought one so I'm not too comfortable posting it on here. I need to get it working by tomorrow.
