Function: tagCloud

[Zegnåt]

Looking good, I was actualliy thinking of writing a tagcloud function myself but it seems you beat me to it!

I have a few things I want to say though:

Code:

\\ example   $jsLink=" onclick=\"searchTag('".$tag."');\" ";

Slashes the wrong way, wouldn't this give problems if I were to copy your script into my functions.php?

Code:

$query=$myPages->item;

You define a variable that you're not going to be using anywhere?

Code:

$components = subval_sort($myPages->xpath("//*"),'slug');

You seem to be using subval_sort() but I thought we established the fact that it doesn't work on an array of SimpleXMLElement objects (as are returned by your XPath call)?
