Reading xml with attributes in php

I have a xml. as shown in the attachment .. How can I read the contents via php

http://ift.tt/1DYumnB "XML"

Now I read this xml:

 function RecurseXML($xml,$parent="")
{
   $child_count = 0;
   foreach($xml as $key=>$value)
   {
      $child_count++;   

      if(RecurseXML($value,$parent.".".$key) == 0)  // no childern, aka "leaf node"
      {

         print($parent . "." . (string)$key . " = " . (string)$value . "<BR>\n");       
      }    
   }
   return $child_count;
} 

RecurseXML($result); 

this result should look:

..
..
.Response.Hotels.Hotel.Room ID = 5556
.Response.Hotels.Hotel.Rooms.Room.Quantity = 0
.Response.Hotels.Hotel.Rooms.Room.MaxPax = 3
.Response.Hotels.Hotel.Rooms.Room.MinPax = 2
