You really want...
Sorry Rich. It occurs to me that, by offering an alternative method, I
didn't really answer your question at all. This should do the job along the
lines you requested:
=====================================
on stripInvalidChars(txt, validChars)
set {res, chars} to {"", count txt}
repeat with n from 1 to chars
set charRef to txt's item n
if charRef is in validChars then
set res to res & charRef
else if charRef is "." and n is chars - 3 then
set res to res & charRef
end if
end repeat
end stripInvalidChars
=====================================
(This seems to be every bit as fast as the suggestion I posted earlier.)
