I have several ActiveResource model in my project. There was so  
strange to me when I called to\_xml on my ActiveResource. The options  
that I passed to to\_xml like :only and :except doesn’t work at all. On  
ActiveRecord, it works really well. Anyone knows?

class Node \< ActiveResource::Base  
self.site = NODE\_SERVER  
end

# node has uuid, name, type attributes

node = Node.find(“3333”)  
node.to\_xml(:only =\> [:uuid])

# after here, i still get all attributes
\<?xml version=\"1.0\" encoding=\"UTF-8\"?\>\n\n \<uuid type=

“integer”\>0\n AAAA\n \n
