You could read how they work in PCRE, as there are a lot more sources for it. It is difficult to wrap your head around, as it matches some text without moving the current position. Also I find that I don't use it that often, so you might just want to put off learning it until you are more experienced using regexes. Who knows, maybe by then it will be easier to understand. I might look into making it easier to understand. (I'm all talk though, so I wouldn't hold your breath)
