Using syntax declarations as range?

[Ph. Marek]

Hello everybody!

I'd like to use a defined syntax group as a range; eg.
        {cComment}s/me/you/g
to substitute every "me" by "you" in C-comments.

I found SrchRplcHiGrp (http://www.vim.org/scripts/script.php?script_id=848) 
but that does only search/replace ... where I'd hoped for a bit more, like 
spell checking, getting a virtual buffer (filled with references to the data 
of another file), folding everything else away etc.

Is there some trick?

Thank you for all answers!


Regards,

Phil
