Characters and Words

Length: 00:04:27

Lesson Summary:

Before we start drafting the regular expressions to convert an HTML document into something else, we need to learn each of the metacharacters we can use to break down and demonstrate a pattern, starting with the basics: How to match word characters (which are letters and numbers). In this lesson, we look at a product list, and, using nothing but the word-related regular expressions and grep, figure out how to pull out the information we need.
