RegExRX is a regular expression editor with many features designed to help in the development and storage of regular expressions. Based on the PCRE library, RegExRX will allow a user to craft patterns that are compatible with most regular expression flavors and will let them easily copy those patterns to and from other languages like Perl, Ruby, PHP, JavaScript, AppleScript, 4D, and Xojo.
