Your question is a simple problem, actually, that hides a hard problem.
Creating a regex from a bunch of strings is simple, just take all the words
and OR them together, so in your example:
Word1 | Word2 | Word5 | Word8 | Word11 | Word19 | Word23 | Word45 | Word77
Unfortunately, there is no known reliable way to simplify a regular
expression (at least, not in 2002 when I took computer theory, if you find a
way, let me know). In addition, you are going to run into trouble.....how
will the computer know that it should convert the list into Word[0-9]{1,2}
instead of Word[1,2,5,8,4,7][1,9,3,5,7]?"
If I REALLY had to do this, I would consider using a neural network first.
It is a hard problem.
