regular_expressions_cookbook Over the past decade, regular expressions have experienced a remarkable rise in pop- ularity. Today, all the popular programming languages include a powerful regular ex- pression library, or even have regular expression support built right into the language. Many developers have taken advantage of these regular expression features to provide the users of their applications the ability to search or filter through their data using a regular expression. Regular expressions are everywhere. Many books have been published to ride the wave of regular expression adoption. Most do a good job of explaining the regular expression syntax along with some examples and a reference. But there aren’t any books that present solutions based on regular expressions to a wide range of real-world practical problems dealing with text on a computer and in a range of Internet applications. We, Steve and Jan, decided to fill that need with this book. We particularly wanted to show how you can use regular expressions in situations where people with limited with regular expression experience would say it can’t be done, or where software purists would say a regular expression isn’t the right tool for the job. Because regular expressions are everywhere these days, they are often a readily available tool that can be used by end users, without the need to involve a team of programmers. Even programmers can often save time by using a few regular expressions for information retrieval and alteration tasks that would take hours or days to code in procedural code, or that would otherwise require a third-party library that needs prior review and management approval.
