Learn how to find and manipulate text quickly and easily using regular expressions. Author Kevin Skoglund covers the basic syntax of regular expressions, shows how to create flexible matching patterns, and demonstrates how the regular expression engine parses text to find matches. The course also covers referring back to previous matches with backreferences and creating complex matching patterns with lookaround assertions, and explores the most common applications of regular expressions.
If you're a Premium member of the lynda.com Training Library or if you're watching this tutorial on a disc, then you will have access to the exercise files that are used throughout this title. The exercise files for this title are arranged by chapter and by movie, and you can find the exercise files that correspond to the movie that you're watching by first looking for the chapter number and then the movie number. Many of the exercise files will include a file called demo.txt. These files contain the text and regular expressions that I demonstrate in the tutorials. Some will also include other text files that are used as assets during the tutorial.
It is always a good idea to make a copy of these files so that you still have the original to refer back to if you make changes. The only software that you will need for this tutorial is a regular expression engine of some kind. In Chapter 1, we'll talk about the available options and set up a regular expression engine that we can work with. The engine that I will be using is also included in the free exercise files to all members. If you're a Monthly or Annual subscriber to lynda.com, you will not have the exercise files that are accompanied with this tutorial, but you can follow along with me. Most of the exercise files we will create during the tutorials, so as long as you continue to work along with me, your files will mirror what is in the exercise files.
You will not, however, have the text assets, but you can substitute your own text or find a copy of the same text in public domain. Remember, you can pause the movie or rewind if you need more time to copy something down.
