Writing Regular Expressions

Could you tell me how I would write a regular expression for the string below in ant? I have a property called typeSplitFirstPart. I want to insert a couple of values after the property typeSplitFirstPart which can either be Product_A or Product_PD or Product_CD (see below). 

CSDT_FLAG_PRODUCT_FF_FWUIDS=Product_A:*;Product_PD:*;Product_CD:*

Currently I have this, but it is not working. 

   <replaceregexp file="x" flags="s" match="([^\.]*)\$\{typeSplitFirstPart:\*?\}([^\.]*)" replace="$HELLOEVERYONE\2"/>

These are pure regex pattern assuming * is any character but semicolon ([^;])

First part is mandatory, at least one product is mandatory, and product can't be empty:

^([A-Z_]+)=(?:(Product_[A-Z]+):([^;]+);?)+

First part is mandatory, products are optional but not empty:

^([A-Z_]+)=(?:(Product_[A-Z]+):([^;]+);?)*

First part is mandatory, products are optional and they can be empty:

^([A-Z_]+)=(?:(Product_[A-Z]+):([^;]*);?)*

Just note that the group starting with ?: is not returning anything for optimization.
