i have word documents with spare parts information and i am stuck with a particular problem

Where ever a particular unit ocurs its displayed as

UnitInfo 1.7

or

Unit 1.7

I need to identify and tag it like this

UnitInfo (Unit Head-1-Part-0007)

or

Unit(Unit Head-1-Part-0007)

How can i get this done. There many documents such as there and it would be great
if i can get this macro done.


Any help with this would be appreciated.
