.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.

RE: RegEx...

IMHO "SQL-like" syntax would be MUCH MORE usefull for regular expressions. Existing syntax is...crap. It's just like some kind of weird cipher, very hard to use and understand.

If you mean by "SQL-like" the syntax SQL uses for the LIKE clause, that's exactly the same pattern matching syntax that 'wildcards' use, except with '?' replaced by '_' and '*' replaced by '%'.

As far as I know, SQL doesn't have regex matching, although, apparently, most SQL implementations have one non standard form or another. MySQL uses unix regexp syntax, for instance:

while regular expression syntax can be hard to read, it's actually pretty good for what it does, and no one has ever come up with a better syntax for regular-expression based pattern matching.
