Please comment if you require a demo file for previous versions of FileMaker.
The attached demo file works only with FileMaker 19. For FileMaker beginners, regular expressions can be an easy way to reliably validate fields or scrape certain values from data without advanced FileMaker skills. The use of regular expressions will make your work as a developer more efficient. Regular expressions are useful for both FileMaker power users and developers. In the demo file, you’ll find support for MatchAll, if that is useful for your solution. I’ve included a demo file that illustrates the concepts in this article. Our next blog posts may cover topics such as Match, MatchAll, Replace, and ReplaceAll. In this blog post, I’ll be only demonstrating RegEx tests for the sake of simplicity. Regular expressions can be implemented in FileMaker without advanced FileMaker or JavaScript development skills. It is a technique developed in theoretical computer science and formal language theory.” Source: Wikipedia Regular Expressions (RegEx) in FileMaker Usually such patterns are used by string-searching algorithms for “find” or “find and replace” operations on strings, or for input validation. “A regular expression is a sequence of characters that define a search pattern. For example: Redact all emails in My email addresses are and The result would be My email addresses are and.Finding and replacing a text pattern (RegEx replace and ReplaceAll).For example: Check if IP addresses exists in I'm using the 1.1.1.1 and 8.8.8.8 public DNS servers and return them, the RegEx function would output both 1.1.1.1 and 8.8.8.8.Finding certain patterns (RegEx match and MatchAll).For example: is a valid email format while is not.
RegEx can be used in FileMaker for a variety of purposes.
Regular expressions (known as RegEx or RegExp) are patterns used to match character combinations in strings.
