I have the following problem:
I am working with openedge Progress-4gl, version 11.3. I am trying to use a regex to check if the entered string is valid according to our requirments.
The string should be exactly 6 characters long, with only numbers. So I came to this regex: [0-9]{6}. According to online regex testers it should work (I know it will also put strings that are longer than 6 characters as true, I just removed the extra characters to make it more clear what the problem is).
Now when I use this regex in progress, it is as if the {6} part is simply ignored/removed. so it will validate any string with a single number in it.
Full code:
DEFINE VARIABLE regexp AS CLASS System.Text.RegularExpressions.Regex NO-UNDO.
regexp = NEW System.Text.RegularExpressions.Regex("[0-9]{6}").
results:
regexp:IsMatch("123456") => returns true
regexp:IsMatch("123") => returns true
regexp:IsMatch("1") => returns true
regexp:IsMatch("") => returns false
Does anyone have experience with this kind of problem? I could solve it using following regex: [0-9][0-9][0-9][0-9][0-9][0-9], but that is just silly.
Thanks in advance
