Re: best data validators?

We were never able to find a suitable validation project for our needs. In
the end we went with regular expressions for almost everything. They were
easy for us to store and manage, and we run them on the server and in the
browser. We actually have a list of expressions for each type, and if any
one of them matches then validation succeeds. This has been very flexible
for us.
