Hi!
Im trying to do a string validation with regular expressions. But i cant figure it out yet so i come here for a little help...
What i want to do is validate this format of str
0-9 space 0-9 space 0-9 space 0-9 space (+ or -)
so one example 3 2 3 3 + or 4 3 2 2 -
the trouble is with the plus and minus character, i have to validate one or another. A kind of OR betwen + or -
any ideas??
thanks!
