Hi all, That's about the whole story, but I'll make it short. For example, I have a list like this :
123ABCDEF456 123456 654WXYZ321 987654321 ABCDEF123456 WXYZ321 By user's INTEGER input , I will have to find how many similar patterns are matched within the list according to certain chars (user's input ) : For example, I input '3', then I will get the result like this : Res1: 123ABCDEF456 is similar to 123456 Res2: 123ABCDEF456 is similar to ABCDEF123456 Res3: 654WXYZ321 is similar to 987654321 Res4: 654WXYZ321 is similar to WXYZ321 In case , if a pattern match happens, then the elem in list will not be shown again even another match happens. Okay, thaz my homework for how to deal with the output. The question I want to ask is how to tell ( or is this a good starting point ) the regex to compare the patterns freely ? So I can get 654WXYZ321 match 987654321 and also match WXYZ321 ? I hope I can explain my question well. Thanks in advise, Li
