It hasn't yet been tried. But Hartmut once wrote an interfacing layer so 
that xpressive regexes can be embedded into Spirit rules. The intention 
was to use xpressive as a lexer for Spirit in Wave, Hartmut's 
pre-processor. It hasn't been attempted yet, AFAIK.

The future for xpressive and Spirit looks very interesting. Joel and 
company have been planning Spirit-2, and we plan to use some ideas from 
xpressive to give Spirit-2 optional exhaustive backtracking semantics. 
The plan is to bring these two libraries closer together.
