recursive descent parser

(grammar)
A "top-down" parser built from a set of mutually-recursive procedures or a non-recursive equivalent where each such procedure usually implements one of the productions of the grammar. Thus the structure of the resulting program closely mirrors that of the grammar it recognises.

recursive descent parser

Software that breaks down XML data or source code into a visual tree for clarity. Known as a "top-down parser," a recursive descent parser reads the input from left to right in contrast to a "bottom-up parser" (such as a shift-reduce parser) that starts with the right side of a grammatical entity. See XML, parse and recursion.
