This method returns any
data that is contained within a node. Remember that the getElementByPath()
method returns JSimpleXMLElement objects, and title, artist, and year are nodes
in their own right.
We are now left with one last thing to do. We need to get the track listing for each
album. To do this, we will iterate over the tracks node child nodes:
if ($tracks =& $album->getElementByPath('tracks'))
{
// get the track listing
$listing =& $tracks->track;
// output listing table
echo '';
for ($ti = 0, $tc = count($listing); $ti < $tc; $ti ++)
{
// output an individual track
$track =& $listing[$ti];
echo '';
echo '';
echo '';
echo '';
}
echo '

Track	Length
'.$track->data().'	'.$track->attributes('length').'

';
}

We retrieve the tracks node using getElementByPath(). We get each track using
the track attribute. We get the name of the track using the data() method. We get
the track length attribute using the attributes() method.
