Sorry - re-reading it, I realized that I accidently inserted html tags that are not showing up.

I found the Greedy section to be quite confusing. First of all, I think you probably have a couple slash-s'es in your html that is causing it to not print and makes the last couple paragraphs very difficult to understand and read.

Also, I'm still confused about why there is a match at all in the first example. Why doesn't the engine continue backwards past the whitespace and look for a <\/tag> string?

Finally, why does the last example (still in the Greedy section) work? If, when creating the example string, I carraige return after the <\/tag>, there shouldn't be a whitespace to match on, right?

Finally, finally, thanks for putting this together... it's really speeding my ramp along...
