Description:
------------
I would ask if you could the following method which returns a reference to the currently active (getCurrentUrl()) node in the $_menu array.
That allows one to change e.g. the title of the active element before rendering the menus, or to get the title of the active element at all.

/**
* Returns reference to the active node element
* (the one where getPath() points to)
*
* @param array $current The array node where the recursion works on currently
* @param array $arPath The value of getPath()
* @param int $nLevel The current recursion level
*
* @return array Reference to the current node array
*/
function &getActive(&$current = null, &$arPath = null, $nLevel = 0)
{
if ($arPath === null) {
$arPath = $this->getPath();
}
if ($current === null) {
$current = &$this->_menu;
}
if ($nLevel < count($arPath)) {
return $this->getActive($current[$arPath[$nLevel]]['sub'], $arPath, $nLevel + 1);
} else {
$strUrl = $this->getCurrentURL();
foreach ($current as $id => $dontuseit) {
if ($current[$id]['url'] == $strUrl) {
return $current[$id];
}
}
$current = null;
return $current;
}
}//function &getActive(&$current = null, &$arPath = null, $nLevel = 0)
