LOTS of theory, may not be the best place to begin
If you're trying to learn REGEX, this book may not be the place to start. Friedl's book is generally recognized as *the* single most authoritative book on REGEX *theory*. But the book's excruciating and labyrinthine discussion of every possible detail of REGEX theory, including corner-cases, may simply overwhelm you.

If you really want to work with REGEX's most complex capabilities, "Mastering" will be a great complement to your other REGEX learning resources and tools.
