Ed Sanders 3c66a297c9 Merge getDataFromDom and getModelFromDom
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.
