Excerpt of article text...

Today, we take an updated look at regular expressions on REALbasic. First, we learn the concept of a regular expression and how it can serve our needs.

We also learn how to use these classes to do a typical search and replace task. And we finish with a step-by-step look at six basic regular expressions.
