    Ah, I hadn't realised you wanted that:( You won't get two arrays back from one match. I'd get everything in to a single array by replacing NOT with (?:NOT|AND|OR), and then use grep to split it up how I wanted.

    Here's some tips on how to format your posts correctly.

    Update

    You should tell us exactly what output you want from the string you gave.

    hi,

    I want in separate arrays.

    o/p:-(1st array)
    (control OR regulat) (blood AND marrow)
    (2nd array)
    (transcription AND factor) (TATA OR TBP) 
    $_ = '((transcription AND factor)NOT(control OR regulat) AND (TATA OR 
+TBP) NOT (BLOOD AND marrow))';

my @caps =  m/NOT   # "NOT"
              \s*   # spaces?
              (     # start capturing
              \(    # "("
              [^)]+ # some not ")"s
              \)    # ")"
              )     # end capture
             /xg;

print join "\n", @caps;
