Compiler Design – Types of Parsing. Recursive descent parsing : It is a common form of top-down parsing. It is called recursive as it uses recursive procedures to process the input. Backtracking : It means, if one derivation of a production fails, the syntax analyzer restarts the process using different rules of same
Parsing. Recall that parsing is the problem of taking a string of terminal symbols and finding a derivation for that string of symbols in a context-free grammar.

A recursive descent parser is a type of parsing tool that works on a recursive basis, in other words, on the basis of using one instance of a command or event to14 Sep 2015
The parser refers to the parsing table to take any decision on the input and stack element combination. In recursive descent parsing, the parser may have more than one production to choose from for a single instance of input, whereas in predictive parser, each step has at most one production to choose.
