Regular Expression Resources

There are many excellent resources available for learning more about .NET regular expressions. Here are a few:

Design and debugging tools

• Expresso (Hey, I like it best as do thousands of users who've sent me email, but I can't claim objectivity. I think the Expresso "Builder" and "Analyzer" make it easier for the beginner and the extensive analyzer-based editing, code generation, and testing tools make it better for the professional programmer.)
• The Regulator (Roy Osherov's tool was inspired by Expresso. It is an excellent program with a different feature set including the ability to search and submit expressions to the Regular Expression Library).
• Eric Gunnerson's Regular Expression Workbench (This was one of the first .NET tools and the inspiration for the Regex parsing tool in several others.)
