It's not really the same, but you might want to look into ExpressionTree http://www-sop.inria.fr/cafe/Manuel.Bronstein/sumit/sumitdoc/node550.html
See also: https://github.com/pippijn/aldor/tree/master/aldor/lib/algebra/src/extree This is, however, just a tree for the expression. There is no information in it where to position the respective subexpression on a output device. That would have to be done by some (tex/html/mathme/...) driver later. So in some sense ExpressionTree is only half of the answer. In Aldor, basically every (algebra) domain knows how to convert an element into an expression tree. However, the print routine for expression trees is currently not 2-dimensional in Aldor. Would be nice to combine the FriCAS and Aldor way.
