If you're dealing with a language, create a lexer that tokenizes your string. Use JFlex, which is a lexical analyzer generator. It generates a Java class that splits a string into tokens based on a grammar specified in a special file. Take the relevant grammar rules from this file.

Parsing is a separate process than tokenization (or lexical analysis). You might want to use a parser generator, after lexical analysis, if lexical analysis is not enough.
