I figured out a solution: https://play.golang.org/p/sWR1hAumYh
I created a type that wraps string and implements the xml.Marshaler interface. Then I just cast my strings to that type. Hey go team, any chance this could be made the default behavior for xml.CharData types so a single cast would do the job?
