Subject: libxml iterate xml tree

Hello Everyone,
i dumped my whole saturday on a small xml problem :-)

i have a xml document

e.g

<car>
   <door id=1>
      <door_handle id=1 color='black'>
      </door_handle>
     <door_handle id=2 color='blue'>
      </door_handle>
   </door>

   <door id=2>
      <door_handle id=3 color='green'>
      </door_handle>
   </door>

</car>

now i want to get all door_handle from each door ?
i tried to iterate it with

running_config_xml = XML::Document.file(@running_config_file)
   car = running_config_xml.root

car.each{|door|
    door.each{|door_handle|
    puts door_handle['color']
    }
}


fist it looks working but every second door_handle had no color ..
i probably iterate it wrong..

is there a trick to do this ??

thanks ahead


Philipp
