php - Is there a better way to loop though this XML list -


here's loop

 function list($input)  {   //i'm sure there's better way of doing this...      $list =  simplexml_load_string($input);     foreach($list->nation $nation){         foreach($nation->region $region){             $temp['url']=  (string)$region['url'];              $temp['name'] = (string)$region['name'];              $temp['nation'] = (string)$nation['name'];             $out['regions'][] = $temp;                       }         $temp['url'] = (string)$nation['url'];         $temp['name'] = (string)$nation['name'];         unset($temp['nation']);           $out['nations'][] = $temp;     }     return $out;         }

sample data:

<?xml version="1.0"?> <regions>   <nation url="canada" name="canada" >     <region url="abbotsford" name="abbotsford" />     <region url="barrie" name="barrie" />     <region url="brantford" name="brantford" />     <region url="calgary" name="calgary" />     <region url="charlottetown" name="charlottetown" />  </nation>  <nation url="ireland" name="ireland">     <region url="cork" name="cork"/>     <region url="dublin" name="dublin"/>     <region url="galway" name="galway"/>     <region url="limerick" name="limerick"/>     <region url="waterford" name="waterford"/>  </nation>

thanks help

function list($input) {     $list = simplexml_load_string($input);      // guarantee fixed output format     $out = array('regions' => array(), 'nations' => array());      foreach ($list->nation $nation){         foreach ($nation->region $region){             $out['regions'][] = array(                 'url'    => $region['url'],                 'name'   => $region['name'],                 'nation' => $nation['name']             );         }          $out['nations'][] = array(             'url'  => $nation['url'],             'name' => $nation['name']         );     }      return $out;         }
