Extract number out of undefined string chain

Share icon

Hi

I d like to extract a number out of a string looking like

String Name = "Shot_Exp_System_s12345"

I want to get 12345, which will always be a 5 digit number
however the string in front of it may change, though it will most of the time have " _s" just before the number

any idea ?

I tried


String Name = "Shot_Exp_System_s12345"
Variable var
sscanf Name, "%*s[_s]%5d", var
Print var

it only sees the string and gives 0
This works for integer numbers, assuming that there are no decimal digits in the prefix string:
Function Test()
    String Name = "Shot_Exp_System_s12345"
    String str
    Variable var
    sscanf Name, "%[^0-9]%d", str, var
    Print str
    Print var
End
