Topdown parsing 1 compiler design muhammed mudawwar topdown parsing va parser is topdown if it discovers a parse tree top to bottom a topdown parse corresponds to a preorder traversal of the parse tree a leftmost derivation is applied at each derivation step vtopdown parsers come in two forms predictive parsers predict the production rule to be applied using. The way the production rules are implemented derivation divides parsing int. Parser is that phase of compiler which takes token string as input and with the help of existing grammar, converts it into the corresponding parse tree.
