Ok the default order for the results is now doc order.  Sorting by other
means probably isn't too difficult anyway, as you can use the usort()
function that takes a callback of two elements that you can then write your
own function to compare elements with.

So you would do something like this (haven't tested this...):

$XPathObj = new XPath;

function cmp($a, $b) {
    global $XPathObj;
    $sA = $XPathObj->getData($a.'/SomewhereElse');
    $sB = $XPathObj->getData($b.'/SomewhereElse');
    return (strcmp($sA, $sB));
}

$aPaths = $XPathObj->evaluate('something or other');

usort($aPaths, "cmp");
