I found the solution, you should write the code like this:

class VolPoint
  includeXML::Mapping
  text_node :Interp, "@Interp", :default_value=>nil
   text_node :Strike, "@Strike", :default_value=>nil
   text_node :OptionType, "@OptionType", :default_value=>nil
   text_node :VolValue, "", :default_value=>nil
 end
