In trying to parse a string with a grammar, if one starts with the grammar and tries to fit it to the string, this is top-down parsing. For instance with a Context-free Grammar, one starts with expansions for the initial symbol, and builds down from there trying to find an expansion which will get to the symbols in the string.
