Regex Tester is a tool to help you testing, evaluating and validating your regular expressions. You can check whether your regular expression is valid; run it again some text input, a local file or a web resource and display the result tree of matches and groups clearly. You can also locate any of the matches or groups in the original text.
It supports 3 styles of regular expressions: perl compatible regular expression(PCRE), regular expression with python extension and regular expression with .net extension(requires mono installed).
