Good to see a post from you again, Howard!
Regular expressions are tempting for that sort of evaluation, since they
are very easy to include in your code using the PCRE dll, and
undoubtedly very powerful. The trouble is that few people know how to
use them, so that if the capability is present in your scripts and
profiles you end up doing a disproportionate amount of support for
expression debugging, rather than for your product. We settled for a
form of segment aware wildcard matching which, whilst pathetically
limited by comparison, is good enough for the jobs it has to do and does
not require any great support effort.
