We study regular expressions. Management

This brief directory presents the most important information about regular expressions. The book describes the procedure for compiling and checking regular expressions, and the basic concepts are explained in detail and are supported by visual examples taken from the practice of processing the source text. At the end of the book, solutions to often found practical problems are given using regular expressions, and their main implementations in programming languages ​​and applications are also briefly described.
The book is written in a simple and affordable language. It will be useful not only to beginners, but also to those who have already used regular expressions in their practice of applied programming.
Connoisseurs of regular expressions have long included them in their arsenal of funds to perform a variety of, sophisticated types of text processing and manipulating in almost any programming language and on any computing platform. But this is only one, pleasant, side of the matter. And the reverse, unpleasant, the side is that regular expressions have remained an exceptional tool for too long for the most technically competent users. But so it was so far.
This book will help you learn to use those regular expressions that you really need to know, starting with the search for simple coincidences with a given text and ending with more complex tasks, including the use of reverse links, conditional calculations and processing with a lead.
Working out the material of each lesson in this book, you methodically, systematically and easily learn to solve practical problems using regular expressions.
Regular expressions are not as complicated as it seems. In order to skillfully use them, it is enough to understand the task and its best solution using regular expressions.
clear, practical examples implemented in different languages
