Count duplicate values in array

Counting values with the following code turns no results to my array. Would appreciate any help on what I did wrong thanks. 

$xml=simplexml_load_file("sitemap.xml");

$arr = array();
foreach($xml->url as $child)
{
    if (isset($child->loc)) {
        echo "true";
        $arr[] = $child->loc;
    } else {
        echo "error";
        echo  $child->loc; 
    }        
}
print_r(array_count_values($arr));

Solution formed after the answer of jack. Added this code to check for duplicates.

if(count($arr) != count(array_unique($arr))){
      echo "Duplicates";
   }

May be expecting like this 

$xml=simplexml_load_file("sitemap.xml");

echo "<pre>";
var_dump($xml->url->loc[0]);
var_dump($xml->url->loc[1]);
var_dump($xml->url->loc[2]);

echo "</pre>";

$arr = array();

foreach($xml->url as $child)
{
    foreach($child as $tmp){    
        if (isset($tmp)) {
            echo "true";
            $arr[] = (String)$child->loc;
        } else {
            echo  "error<br/>";
            echo  $child->loc; 
        }    
    }    
}
print_r(array_count_values($arr));

You have to cast the item values properly, otherwise you would be storing SimpleXMLElement objects in your array:

$arr[] = (string)$child->loc;
