I have another question...for the same input

(S=(SN=a1)
     (I1=(IN=s%1)(NM=1)
          (HL=(HLD=kkk kjkjk)(ST=st1)(HI=REM SSS)(H_M=9)(HL=72)(EB=0)
+(ER=0)(HI=E043-93A-DF0-0AB63E)(PE=aaa)(HN=DEE)(SS=NS)(SED=(APR=(PAD=k
+kk)(PN=9905)(HH=llkjk))(DD=(LLL=kkk))))
           (ppp=1)(RAW=kkk)(DN=kkk)(RIN=ppp))
         (PPP=1)
         (AA=LLI)
(SN=a2)
     (I1=(IN=s%1)(NM=1)
          (HL=(HLD=kkk kjkjk)(ST=st2)(HI=REM SSS)(H_M=9)(HL=72)(EB=0)
+(ER=0)(HI=E043-93A-DF0-0AB63E)(PE=aaa)(HN=DEE)(SS=NS)(SED=(APR=(PAD=k
+kk)(PN=9905)(HH=llkjk))(DD=(LLL=kkk))))
           (ppp=1)(RAW=kkk)(DN=kkk)(RIN=ppp))
         (PPP=1)
         (AA=PPP))

How do i retrieve the value of "AA" or "ST" For each (SN) above? Thank you
