    You can not. Not with regular expressions, you chose a completely
    wrong tool for the job. When the regex machine runs into a mismatch
    it abandons that branch. You would be very unhappy about performance
    of any regex machine that would provide the feature you're looking
    for.
    
    Hmm, a quick googling finds agrep and TRE, I have no idea if these
    would do what you need, you don't seem to provide enough context,
    and I have a feeling you are asking for a wrong solution to your
    problem.
