Reading Room


This book is for those who are new to Regular Expressions.  If you are an intermediate and looking for help, you don't want this book.
Readers are started from the very beginning, taking you from the introductory topics such as 'What is Regular Expressions?" to finally writing full sed and Perl scripts that takes a full text file and convert it into a full HTML file. After struggling with other books on Regular Expressions, I found this to be a breath of fresh air and just what I was looking for.  It helped me grasp the basics, easing me into it and helping me to take it one step at a time.  Glad it is part of my instructional tool kit!
