Title: It works, it's just that...

It's formatted for Whitespace matching in .NET. If you want to use it in .NET you will need to set the IgnorePatternWhitespace flag to true. If you are using it in something other than .NET, simply remove the embedded whitespace and comments: (\b\w+\b)\s+\1 You can easily test this out by following the test link at the top of this pattern. Good Luck! - Darren
