I have a pattern to validate a simple class of email addresses. The pattern allows alphanumeric characters, dashes (-), underscores (_), and dots (.) before and after an @ character. The tricky part is that only one dot character can appear in sequence. So,<BR>j.doe.@email.com is ok, but<BR>j..doe@email.com is not<BR><BR>The other restriction I want to impose is a min and max length of the input email address. I do not know how to add this to the pattern I&#039;ve got.<BR><BR>Here is the current pattern:<BR>^[w-_]+(?:.[w-_]+)*[@](?:[w-_]+.)+[w]+$<BR><BR>Can you tell me how to impose the min/max length on the overall expression?<BR><BR>Thanks,<BR>k
