Description Author  

This package can parse source code in a given language based on the language syntax defined in the BNF format (Backus-Naur Form).

It takes a grammar with syntax rules defined in BNF format and parses the syntax to build a XML parse tree.

The main class also takes as parameter a reference to a lexer object that splits the source code text in tokens.

A SQL parser and a RTF parser are provided as examples.

BNF (Backus-Naur Form) defines a syntax for representing the grammar of the commands of a given programming language.

This implements a parser to process a language grammar in the BNF format, so it can be used to implement parsers and compilers for that language.
