XPath expressions that return scalar value

Hi,

DOMXPath->query() method according to documentation returns 
DOMNodeList() object. But how can I access result of expression that 
returns just string, number or boolean?

E.g. DOMXPath->query("count(//*)") will return empty node-set from PHP 
point of view.

Do you plan to add new method, say evaluate, that will be able to return 
scalar types? Something like:

echo "Total number of element in document: " . 
$xpath->evaluate("count(//*)");

echo "Title of the first chapter: " . 
$xpath->evaluate("string(//chapter[1])");

Without such method XPath API in PHP is very limited compared to other 
XPath API in languages like Java or .NET.
