General answer :
compiler = lexer (lexical analyser) + parser + code generator
lexer = scanner (implemented usually as FSM) + tokenizer
compile process :
source code -> lexical analysis -> parsing code tree -> generate compiled code for linking (optimize where necessary)
It seems you need both the lexer and parser; I recommend you the following links
http://en.wikipedia.org/wiki/Compiler
http://en.wikipedia.org/wiki/Lexical_analysis
I recomend you to use a compiler generator, check http://en.wikipedia.org/wiki/List_of_parser_generators
