Nice reference page, thanks!
I hope Hardik has his answer by now, but for other people with the same question, the Australian postcode is one of the easiest regular expressions, as it is simply a 4 digit code. The lowest one I know of is 0800 and the highest is 9999.

The regexp would simply be “\d{4}”
ie; digits exactly of quantity 4.

onblur is a JavaScript function and I recommend against using JavaScript for anything that is required to happen. There is no guarantee that the JavaScript code will run in a users browser. Instead it is best to put the clean-up code in the submit function just before inserting it into the database. You can now be assured that the data will be formatted properly. An example clean-up algorithm:

' handle phone variations
If phone.Contains("(") Then
  ' extract digits
ElseIf phone.Contains("-") Then
  ' extract digits
...
End If

Do you have examples of the clean-up functions that changes the information into the correct format for storing in the database? Can this be done “onBlur”? I am very new at ASP.Net and have used regular expressions in javascript but am not sure how to reformat data input in ASP.Net.
