Is it possible to divide/split a text somehow?

Is it possible to divide/split a text somehow? I use the Project/properties/version as 1.0.0 (Major.Minor.Fix) and would like to be able to split this into three separate objects containing major, minor and fix as separate numbers. A function for dividing the parameter based on a limiter or a function for retrieving for exsample the first two characters from the left or the 3 characters from position 3.
