About this document
With this article, I would like to give a quick introduction into regular expressions and how you can use them in InterSystems Caché. The information provided herein is based on various sources, most notably the book “Mastering Regular Expressions” by Jeffrey Friedl and of course the Caché online documentation.
This document is not intended to discuss all the possibilities and details of regular expressions. Please refer to the information sources listed in chapter 5 if you would like to learn more.
Text processing using patterns can sometimes become complex.
