For example the following would be a valid address list: What's really nice about recursive descent parsers is that we can take the grammar rules and turn them into code in a fairly straightforward manner.
Here is pseudo-code for the above address list example: def get-address-list(): address_list =  # get address address = get_address() if address is None: return None address_list.append(addr) while True: # get delimiter delimiter = get_delimiter() if delimiter is None: break # get address address = get_address() if address is None: break address_list.append(address) return address_list Just like that, one by one, we slowly built grammar for every part of an email address.
However, if you want to restrict users to entering an email address, then use a validation rule that ensures that what a user enters into the field matches the pattern of an email address, and prompt them to correct it if it is not.
Validation rules are designed to check for certain conditions within a form and, if those conditions are met, notify the users so that they can take corrective action.
Adding validation rules to controls in a form template ensures that the data collected is accurate and consistent.
