What I'm after is a method that gets a child node of a certain "current =
=

node" that has a certain name. It is for a general purpose solution I'm =
=

making.

As an example, in

<books>
<book>
<title>Bananas, and how to peel them</title>
<author>John Doe</author>
<review>
<author>Perry White</author>
<title>New banana peeling book revolutionalises world of banana =

peeling</title>
</review>
</book>
</books>

if i have a DOMNode object $book that refers to the above book node, i'd=
=

want the fastest way to get me a DOMNode object that refers to its title=
=

child (but of course not to the review's title, which is what =

$document->getElementsByTagName would give me).

With SimpleXML, I could of course just do $doc->books->book->title, but =
I =

don't want to use SimpleXML because it is so awfully terrible at anythin=
g =

other than reading out some data (try deleting a node or adding features=
, =

for instance). So, what's the fastest/best/etc way to do it with DOM?
