Sure, and you'd have to expose the developer to that tree structure for this to happen.

You could take steps to make it look closer to the original serial data (eg, the DOM doesn't have opening and closing tags, but DevTools shows it that way because developers expect it). Or you could come up with a more efficient but less familiar form.

There may be "good enough" parallels in other languages though, for example structured-haskell-mode for emacs.
