Linux 在awk中重置标志

我有以下使用awk的函数：

getStageMode() {
targ=$1; shift
       mode=$(awk '
        /[<]app-deployment/{a=1}
        a && /[<]name[>]'"${targ}[<]"'/{n=1}
        a && n && /[<]staging-mode[>]/{ 
          sub(/[<]staging-mode[>]/,"", $0)
          sub(/[<]\/staging-mode[>]/,"",$0)
          print $0
          exit
        }
        {print "n=" n }
        ' "${@}")
echo $mode
}

getStageMode（）{
targ=1美元；班次
模式=$（awk'
/[
/[重置n的条件是什么？与
/[<]\/app-deployment/{a=0; n=0}

getStageMode() {
targ=$1; shift
   mode=$(awk '
    /[<]\/app-deployment/{a=0; n=0}
    /[<]app-deployment/{a=1}
    a && /[<]name[>]'"${targ}[<]"'/{n=1}
    a && n && /[<]staging-mode[>]/{ 
      sub(/[<]staging-mode[>]/,"", $0)
      sub(/[<]\/staging-mode[>]/,"",$0)
      print $0
      exit
    }
    {print "n=" n }
    ' "${@}")
echo $mode
}
