The best part of this book is the author's wonderful explanation of Regular Expressions which is also topped of with the amazing examples. This part alone is worth the purchase. I learnt how to use regular expressions effectively from this book alone...BUY IT, TREASURE IT AND YOU WILL READ IT JUST FOR RELAXATION AND IT WILL BECOME DOG EARED AND TATTERED BUT YOU WILL NEVER FORGET IT OR THE WONDERFUL EDITOR IT EXPLAINS...
