Where Can I Find Information About Format for Regular Expression as a Validator


Rob Olsen (3512052) | asked Jun 02 '15, 11:57 a.m.

So using what I could find (and with the help of this forum), I wrote a regular expression that forces a name entry to be Last, First and MI, (i.e. [a-zA-Z]{1,20}, [a-zA-Z]{1,20}[ ]{0,1}[a-zA-Z]{0,2}).  This allows a Middle Initial or not depending if the person has one.  Now I was asked if I could include a "-" in the last or first name.  Is there somewhere that I can look to find variations of this "regular expression" as to what is allowed and what is not?  Where I can include something like a "-" appearing anywhere in the name?  I tried something like ['-'-z] and it appears to work in the "sample text" but fails when I try it on the actual project. 

Basically where can I find some documentation on setting this this regular expression to valid different strings?

If memory serves, for most RE to have - recognized literally in a range of characters it must be the first character following the [.  

e.g. [-a-zA-Z]

This has a few more methods

Thanks Kevin, I tried that and it works in the Sample Text but then I went to implement it and it fails.  BTW - you say "if memory serves", is there nothing documented out there that I can find this information?  The example was pretty clear as far as using a formatted digit and numeric entry, but what about allowing for other "non-characters" and "non-digits"?  Is there nothing I can reference to figure out how to format something of that nature?

I found at least one reference ( that I added after posting answer ) that I found googling for "allow dash in regular expression"

Kevin, thanks, I added "-" and that worked.
