[jQuery] Re: Trouble selecting a P inside a repeating DIV

The nth-child index is relative to the whole collection of children
elements, not just the one you're selecting. With your new mark-up
you're better off doing this:

$(".insidepost ul + p")
//or
$(".insidepost p:first")
.addClass("caminfo")
.next('p').addClass("cambuy")
.next('p').addClass("cam..");

Looks a bit clearer to me and is safer in case you add other elements
before the paragraphs.

This is the first real possible use I've seen of the CSS3 nth-of-type
selector!
