Hello nileshjsr and welcome to the monastery.

I can tell you tried to format your question with HTML tags, but like others have said your data is difficult to decipher.

However, I think I can sort of understand what you are asking for.

Usually I would use the flip-flop operator for this kind of thing, but since you don't want the last line of the blocks I just reimplemented a slightly different version.

Let me know if this works for you...

#! /usr/bin/perl

use strict;
use warnings;

my $print;

while (<DATA>) {
    $print = 1 if /^AIR_TCD/;
    $print = 0 if $print && /record\(s\) selected/;

    print if $print;
}
