Your question is a bit unspecific: The Bison generated parser only reads
the tokens handed over to it, and does not know anything about strings and
such. The parser reads the stream of tokens in a context-free manner, so
the parser itself cannot take into account past or future context
information. But there are several ways to tweak the setup; but then one
needs more information about what one wants to do than what you provide.
