one way would be a before\_filter, e.g.

class ApplicationController \< ActionController::Base

before\_filter :trap\_xml

def trap\_xml  
if params[:format] == ‘xml’ && params[:action] != ‘my\_xml\_action’  
redirect\_to :controller =\> ‘my\_xml\_controller’, :action =\>  
‘my\_xml\_action’  
end  
end

end
