$xml = new SimpleXMLElement($string); //variable $string is nothing but your XML content
$result = $xml->xpath('/propertyList/business/listingAgent/telephone');
//short form
//$result = $xml->xpath('////telephone');
foreach($result as $node) {
  print 'Telephone Atrribute: '.$node->attributes().'<br>';
}
