We've used square brackets frequently in previous lessons, but there's more to them than we've addressed. In this lesson, we get in-depth with character classes and learn how to use them not just to match a range of characters, but also how to negate which characters we want to be matched. We also address how to use subtraction in regex, a feature limited to XML, .NET, JGSoft, and XPath implementations.
