Done with Introducing Regular Expressions, by Michael Fitzgerald.
The subtitle, of the book says it all.

Unraveling Regular Expressions, Step-by-Step

Michael is a funny, patient and pithy author.

The book breaks down the basics of Regular Expressions into its components and then walks through explaining them in examples, line by painstaking line.
Any book that uses Coleridge to teach me Regular Expressions is awesome, so I’m biased :)

Definitely worth a read if you are brand new to the powerful world of RegEx.

Did this short course to get myself upto speed with Regular Expressions, since the books I was trying to read were not quite doing it for me.
It’s short, sweet and extremely thorough.

After this I don’t quite know regex, but I’m no longer lost at sea.

I’ve now picked up a book and I get what they are talking about now.
The book and lots of practice, should get me to where I want to be with Regular Expressions.
I’m sweating this, because I’ve realised, this is an important skill, I need to have.
