Regular expressions are very useful but as I do not have to use them a lot, I often forget the exact syntax required for my particular need.
So today I would like to share a tool to build regular expressions which I have been using many times over, the Regular Expression Designer of Rad Software.
The tool is free, easy to use but yet powerful and intuitive. The contextual help is very short but just perfect and straight to the point for someone who already has previous regex experience. If you are a total newbie in regular expressions, you should read some short introductory material beforehand.
