I have to filter user input to on my web ASP.NET page:

<asp:TextBox runat="server" ID="recipientBankIDTextBox" MaxLength="11" />
<asp:RegularExpressionValidator runat="server" ValidationExpression="?" ControlToValidate="recipientBankIDTextBox" ErrorMessage="*" />

As far is I know SWIFT code must contain 5 or 6 letters and other symbols up to total length 11 are alphanumeric.

How to implement such rule properly? TIO
