How to isolate elements in a 2-element array returned from a function?

I am using a PHP function that will return 2 arrays. Below is my function:

function imserv($id){
    $xml = simplexml_load_file("feed.xml");
    $images = $xml->xpath('//IMAGE');
    $services=$xml->xpath('//SERVICES');

    return array ($images,$services);
}

I use the below code to get results from the services block:

$services = imgserv('5874');

foreach ($services as $servicerow)
{   
    var_dump($servicerow);
}

The problem is that when it try to get only the values of the services, it returns both, services and images together. I need to to use both in two different places so how do I separate it to be used differently?

Below is my feed XML:

<?xml version="1.0" ?>
<FOUND>
<NFO>
<IMAGES>
    <IMAGE>
      <SMALL>images/small.jpg</SMALL> 
      <MED>images/med.jpg</MED> 
      <LARGE>images/large.jpg</LARGE> 
      <EXTRAL>images/extra.jpg</EXTRAL> 
    </IMAGE>
    <IMAGE>
      <SMALL>images1/small.jpg</SMALL> 
      <MED>images1/med.jpg </MED> 
      <LARGE>images1/large.jpg</LARGE> 
      <EXTRAL>images1/extra.jpg</EXTRAL> 
    </IMAGE>
    <IMAGE>
      <SMALL>images2/small.jpg</SMALL> 
      <MED>images2/med.jpg </MED> 
      <LARGE>images2/large.jpg</LARGE> 
      <EXTRAL>images2/extra.jpg</EXTRAL> 
      </IMAGE>
   </IMAGES>

It would be easier if You change function to something like this:

function imserv($id){
$a = array();
$xml=simplexml_load_file("feed.xml");

$a['images']=$xml->xpath('//IMAGE');
$a['services']=$xml->xpath('//SERVICES');

return $a;
}

Then You will be able to write something like this

$imservarr=imgserv('5874');
foreach ($imservarr['services'] as $servicerow)
{   
var_dump($servicerow);    
}
foreach ($imservarr['images'] as $imagerow)
{   
var_dump($imagerow);    
}
