Now getDataFromDom is no longer called externally, we can merge these two methods to provide one API endpoint. Also now we have deleted getDataFromDom we can remove the 'Recursion' disambiguator from the internal function. Also now that the whitespace info doesn't need to be passed around, implement it as a simple return value get function. Change-Id: I9c667e9b90443d12660b731347d7535ccb1a17cd
