You can either override the protected val whiteSpace (a Regex) whose default is """\s+""".r or override the protected def handleWhiteSpace(...) method if you need more control than is readily achieved with a regular expression. Both these members orginate in RegexParsers, which is the base class for JavaTokenParsers.
