Why not do it in LiveCode rather than using regex? Assuming that the
3rd and 9th char of a properly formatted string must be a period, and
all other chars must be alphanumeric:
constant alphNumChars = "abcdefghijklmnopqrstuvwxyz0123456789"
constant alphNumPlaces = "1,2,4,5,6,7,8,10,11"
function testFormat strg
-- format should be: XX.YYYYY.ZZ
if length(strg) <> 11 then return false
if char 3 of str <> "." then return false
if char 9 of strg <> "." then return false
repeat for each item i of alphNumPlaces
if char i of strg is not in alphNumChars then return false
end repeat
return true
end testFormat
call it with:
if testFormat(tInput) then
-- valid string, do whatever
else
-- invalid string, do something else
end if

Dear all,
i have to check for an value in the format XX.YYYYY.ZZZ (e.g.
A1.B35AZ.001 or a1.b35az.001)
I have to check if the value is in the right format. I know i can do
that with matchtext and a regular expression, but
i do not know enough to get the regular expression to work.
Is there anyone who might be able to help?
Regards,
Matthias
