Understanding Strings and Regular Expressions in C++, C#
Linked by Eugenia Loli on Sun 30th Jul 2006 20:57 UTC
.NET (dotGNU too) Regardless of what type of data you're working with or what kind of application you're creating, you will undoubtedly need to work with strings. No matter how the data is stored, the end user always deals in human-readable text. As such, knowing how to work with strings is part of the essential knowledge that any .NET developer needs to make rich and compelling applications. In addition to showing you how to work with strings in the .NET Framework, this chapter will also introduce you to regular expressions. Also, Jeff Cogswell explains how to use regular expressions to simplify and enhance the power of your programmatic string searching, matching, and replacing.

I don't know if you expected a whole book of discussion about regular expressions, but these two links (which are actually parts of book chapters) have enough info to get you started.

No. They have enough misinformation to have you confuse pattern replacement patterns with regular expersions.

I've seen discussions of regular expressions in fewer words that did a better job and didn't cause people to confuse them with the '*' and '?' glob patterns.

Nor do these discussions give you enough to get started, as they don't even cover all of the syntax in the example they gave.

Writing an example that you don't even explain is lousy exposition. period.

http://www.regular-expressions.info/tutorial.html which is the first hit in google for regular expression tutorial is far better and doesn't try to confuse people by comparing regexps to something they're not.

Probably none of you need introductory material to regular expressions, but if you know anyone who does, RegexBuddy, whose tutorial is Cloudy's cited link, is a great (non-free) package if you are learning the things. Or there is the material in Robbins books on Awk which have very nice compact explanations. Though I found the Aho book on Awk much better to learn Awk itself from.
