How to hide attributes that have a null value

Hi,

I would like to know if there is a way to hide certain attribute fields under the Specification Tab of the product page if the attribute has a null value? I am running version 3 of open cart and using Journal theme. The link below is a test product, if you click on the specification tab you will see what I want to remove. I have the attributes organized the group, but not all the items will have data for all the attributes in the group. I would like a automatic way of not displaying them when they have no value. Also I don't want to mess with any core files.

Thank you for your help....Ralph

Well, then better place such in the commercial section of this forum,
to have a better chance, that it will be found by Dev's, not always looking
around here in the 'open' Area for Jobs. It belongs to a paid custom
Theme, so, and paid Code shall NOT be made available to others, possibly
even claiming to be DEV's, or one risks to break the Rules. So, it's nothing
personal, just information!
Good Luck!
