Regex Tools

Playing with Regex is fun, mostly when you are dealing with content parsing (for example: grabbing content from a site and process it into a RSS Feed). By using Regex, you can do a lot of automation, since regex is some kind of string of pattern which can be used for several purposes, mostly for matching, splitting, and replacing data within string data.

If you use Linux and KDE is your desktop manager, then you are quite lucky, since KDE has provide a regular expression tool which can be used to create and validate regular expression, called KRegExpEditor (part of kdeutils package). For Windows, there are also some tools, which you can use, for example:
- RegexBuddy (commercial)
- RegexStudio (commercial)
- PowerGREP (shareware)
- Kodos (GPL)
- StringTool (Online)
- The Regex Coach (GPL), thanks to Moses Yorga Arthesi
- txt2regex (GPL), thanks to Yan
