Seems like you want to copy all ?class values that are are part of any
owl:oneOf enumeration, independent from the value of ?list. In this
case you indeed would have to walk through all owl:oneOf. The fact
that you are type casting (xsd:string) all values makes direct pattern
matching difficult and FILTER is IMHO the only solution.

Could you show us the rules in SWRL so that we can better understand
what you are doing?
Thanks
