Regular Expression Assistance

Using a C350 for Email Encryption Only

I have a regular expression that searches for a number format that could match a medical record number, among other numbers. Getting many false positives due to a matching number being found in many places in the html tags of the email.

Anyone have any good ideas on how to eliminate this? I have quite a few negative lookbehind and negative lookaheads in there already to look for dashes, backslashes, slashes, etc., but still can't weed them all out.

Thanks!

Can you paste in some examples of what you're trying to match against?

Not sure if you're using it but Kodos is a great little tool I use for quickly testing out reg expressions.

Looks nice.
Another tool that we use to test Regular Expressions is called "The Regulator", hosted on sourceforge.net as well. You can find the homepage with some screenshots here: http://tools.osherove.com/CoolTools/Regulator/tabid/185/Default.aspx
