Abstract: The regular expression is the set of text strings that describe a search pattern ¬[1][2], and also can provide special techniques for parsing and validating data. There are several works that have been done on reading text string [3][4][5] using several algorithms like backtracking search, local search, and dynamic programming ... As a result backtracking is an effective algorithm for reading a regular expression text string, and there are exceptional cases that it encounters an infinite loop or a waste of time, this is the case of catastrophic backtracking. And to avoid this type of problem we have proposed an intelligent reading method based on reverse reading of a text string.
