I'm not sure what you mean, can you send some real
examples of the data rather than just a generic pattern?

For example what do A,B and C signify? Are they literals?
Are they uppercase letters? Constant tokens? Something else?

You don't have a pattern like that in your string.
Do you mean the first term {A,BC}?
And should it really be {A,B,C}?

Until we understand the data better we can't be sure
a regex is the best solution.
