note dsb Hey, [hv].... <p> I think this a great short explanation of regex engine expectations. The only part I might tweak is the part that addresses the mostly greedy nature of the Perl engine. <p> Your explanation <i>is</i> right on with regards to the way the engine behaves. You may, however, want to change the term <i>iterations</i> to something else. <i>Iterations</i> usually refers to the repetition of a series of operations. So, while the process of attempting to match against each character could be called an iteration of the regex engine, the characters could really not. <p> I'm not trying to be overly critical or anything. This tutorial would be great for new (Perl|regex) users to read and i guess I just think the use of <i>iterations</i> might be a bit confusing to them. <!-- Node text goes above.
