Hello Everyone,  
i dumped my whole saturday on a small xml problem 🙂

i have a xml document

e.g

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

if i do it like

car.each{|door| if door.child?  
door.each{|door\_handle| if door\_handle.child?  
puts “color #{door\_handle[‘color’]}”

end }

end}

it shows only the elements with content !!  
dont know why but its working …
