VBScript REGEX list intersection

Last Modified: 2012-09-30

I have two strings that actually are lists like :

S1 = "22,45,54,66,32"
S2 = "123,467,54,999"

I need to have a small function, using regex (no split table + loops) that sends back true or false if the lists intersect, which means they have an element in common.

In my example, S1 and S2 do intersects (54 common), but
S3 = "965,99"
should not intersect with S2 as 99 does not match 999.

Thanks for help
