Here are some good learning resources and tutorials for teaching yourself how to write Regular Expressions. These are the best ones that I have found for this topic.
Learning to Use Regular Expressions: gnosis.cx/publish/programming/regular_expressions.html This tutorial is aimed at users and programmers who have begun to work with tools that use regular expressions, but who are not quite comfortable with the intricacies of them. Even users who may have used regular expressions in the past, but have forgotten some of the details can benefit from this as a refresher. Completing this tutorial and lots of practice with varying cases is about all you need to be an expert. The concepts of regular expressions are extremely simple and powerful. It is their application that takes some work.
Regular Expressions - User guide: www.zytrax.com/tech/web/regex.htm This user guide provides an overview of the format and syntax of Regular Expressions specifically as they are used in Apache. The guide and notes are also generally applicable to most supporting applications.
Regular expression Article from Wikipedia, the free encyclopedia: en.wikipedia.org/wiki/Regular_expression This is a very well written about regular expressions and how to write them. Several good web resources are also linked from here.
Regular Expression Tutorial: www.regular-expressions.info/tutorial.html Learn How to Use and Get The Most out of Regular Expressions. In this tutorial, the author teaches you all you need to know to be able to craft powerful time-saving regular expressions. He starts with the most basic concepts, so that you can follow this tutorial even if you know nothing at all about regular expressions yet. Then he also explains how a regular expression engine works on the inside. This will help you to understand quickly why a particular regex does not do what you initially expected.
Demystifying Regular Expressions: www.linuxforums.org/applications/demystifying_regular_expres... In this article a simple usage of regular expressions is described. Its intention is to bring users to try the most powerful search and replace paradigm available and hopefully start using it. The article is written reproducing actual steps I took to complete my task, to show the specifics and possible problems.
