Hi All,

My application has evolved. Earlier I was searching for a string, such as 3.2.P.1.2.3, where the (period + number) after the "P" may repeat one or more times. Now, it can be:
[2 or 3] + [period or no period] + [1 or 2 or 3] + [period or no period] + [P or S or A] + [period or no period] + [number], where the period (or no period) + number after the P,S or A may repeat any number of times. Some examples would be:

3.2.P.1
2.3.S.1.2
3.2.A.1.2.3.4.5
32P1
23S12
32A12345

I thought the expression would be "<[32].[231].[PSA].[0-9]{1,}"; however, this is only picking up strings that have periods in them. I thought the periods in this expression would represent any (or no) character. Would you help me with the expression, please?

Thanks again,
Roy
