- [Kevin] Welcome to Using Regular Expressions. My name is Kevin Skoglund. - Welcome to Using Regular Expressions. In this course we are going to learn how to use regular expressions to find and manipulate text. My name is Kevin Skoglund, in this course, We will start by learning the symbols and basic syntax we are going to learn how to use regular expressions to find and manipulate text. of regular expressions. We will use character sets and repetition expressions We will start by learning the symbols and basic syntax of regular expressions. to create flexible matching patterns. We will use character sets and repetition expressions And along the way we'll examine how to create flexible matching patterns, the regular expression engine parses text and how it utilizes greedy and lazy strategies the regular expression engine parses text, as it finds matches. and how it utilizes greedy We will learn how to capture text and lazy strategies as it find matches. and to refer back to it later by using back references We will learn how to capture text, and we will discover how look around assertions and to refer back to it later by using back references, can help us to create complex matching patterns.
and we will discover how look around assertions And then finally, in the last chapter, can help us to create complex matching patterns. we'll explore some of the most common and most useful And then, finally, in the last chapter, regular expressions by building them up step by step. we will explore some of the most common and most useful regular expressions, Now it doesn't matter if you're a complete beginner by building them up step by step. or if you have some prior experience, Now it doesn't matter if you're a complete beginner, we're going to cover all the fundamentals you need or if you have some prior experience. to write your own regular expressions. We're going to cover all the fundamentals So let's get started learning about regular expressions. you need to write your own regular expressions. So, let's get started learning about regular expressions.
