Suppose i have this input string "3rd position 5th time"
I want to write a Regular Expression to get 3 and 5 in a String like this "3 5" i.e., 3 and 5 both will be in a String but having a space. 3 and 5 may be any numbers like 12 or 13 ony any other numbers. For this i wrote this Regular Expression
Dim regexpression As
String =
"^[0-9]*+[0-9]"
but its not working .I am unable to get the logic.
i have to check if an input string is valid based on the given regular expression.. this is the regular expression.
(a(bb+aaa+((ab)*bb+(aba)*aa)(a+b)*) + (b(aa+bbb+((ba)*aa+(bab)*bb)(a+b)*)
+ is an OR
* is a LOOP, it is optional, it may be done as many as a user wants.
i've tried many ways to solve the problem that my professor gave me but my knowledge isn't that enough to solve this problem..
