Use DOMDocument of php.

$objDOM = new DOMDocument(); 
  $objDOM->load("test.xml"); //make sure path is correct 


  $note = $objDOM->getElementsByTagName("lon"); 
  // for each note tag, parse the document and get values for 
  // tasks and details tag. 

  foreach( $note as $value ) 
  { 
    $tasks = $value->getElementsByTagName("id"); 
    $task  = $tasks->item(0)->nodeValue; 


    $details = $value->getElementsByTagName("name"); 
    $detail  = $details->item(0)->nodeValue; 

    $notes = $value->getElementsByTagName("notes"); 
    $notes  = $notes->item(0)->nodeValue; 

    echo "$task :: $detail :: $notes <br>"; 
  }
