In response to this tutorial over on the PHPro.org website a new post has been made to the PHP in Action blog with an "even cooler" way to do the same sort of DOM fetching - XPath.

I'm a little bit surprised at the claim [the tutorial makes] that it's the "correct" (only) way, since there's at least one more that I find even cooler: XPath. Admittedly, it's slower, yet it's a more powerful language.

A quick example is included, building up from a simple search for anchor tags up to a custom query looking for just the anchor tags with a class of "bookmark".
