Is there any beter way to write this?

before\_filter :set\_locale

def set\_locale  
if(params[:locale] and params[:locale].match /^(da|en|de)$/)  
I18n.locale = params[:locale]  
elsif session[:locale] == nil  
xxx = request.env[‘HTTP\_ACCEPT\_LANGUAGE’].scan(/^[a-z]{2}/).first  
if xxx.match /^(da|en|de)$/  
I18n.locale = xxx  
else  
I18n.locale = ‘en’  
end  
else  
I18n.locale = session[:locale] || ‘en’  
end  
session[:locale] = I18n.locale  
end
