Query: An Excellent Regex Reference

I recommend getting this bookif you feel comfortable with regular expressionsand regular expressions are important to you.As one expects from an O'Reilly Pocket Reference,this book is compact but still covers a lot of ground.For a whole bunch of applications, it provides:* tables of various groupings of regex metacharacters,summarizing their syntax and meaning;* summaries of other regex related features,but not in tabular form;* examples;* a few references in case you need to go deeper.The information is concise and well chosen.This is a reference,but in applications where you use regular expressions less,it may also be useful for expanding your knowledge significantly.It was for me.If you wish, take a look at mymore detailed review on Oakland Perl Mongers.
