Ok I used the code in the comments and tryed adding the scanning for X2 and X3 the same way as for X1 but for some reason the saveto vars are mixed up at the end
The wrong one I get is:
 X3: yes yes yes BEGIN_TAG X1 test test test tes test test X2 no no no no no  nono non no no  nononono no no  no X3 hi hi hi hi hi hi  hi hi hi hi  hi hi

The right one would be:
X1: test test test
test test test tes test test
X2: no no no no
no no no no no nono non no no nononono no no  no
X3: yes yes yes
hi hi hi hi hi hi hi hi hi hi hi hi

The code I have is:

#!/usr/bin/perl
use strict; 
use warnings;
open (FILE, '<', $ARGV[0]) or die "Could not open file: $!";
my $saveX1=0;
my $saveX2=0;
my $saveX3=0; 
my $savetoX1=''; 
my $savetoX2='';
my $savetoX3='';
while (my $line=<FILE>){
  chomp $line; 
  my @parts=split(' ',$line,2); 
  if ( (!$saveX1) && $parts[0] eq 'X1') { $savetoX1=$parts[1]; $saveX1
+=1; } 
  elsif ($parts[0] eq 'X2' ||($parts[0] eq 'BEGIN' && $parts[2] eq 'TA
+G' ) ){ 
       #print $savetoX1."\n" if ($savetoX1) ; 
       $savetoX1=''; 
       $saveX1=0; 
       } 
  elsif ($saveX1) { $savetoX1.=' '.$line; } 

  
  if ( (!$saveX2) && $parts[0] eq 'X2') { $savetoX2=$parts[1]; $saveX2
+=1; } 
  elsif ($parts[0] eq 'X3' ||($parts[0] eq 'BEGIN' && $parts[2] eq 'TA
+G' ) ){ 
       #print $savetoX2."\n" if ($savetoX2) ; 
       $savetoX2=''; 
       $saveX2=0; 
       } 
  elsif ($saveX2) { $savetoX2.=' '.$line; } 

  
  if ( (!$saveX3) && $parts[0] eq 'X3') { $savetoX3=$parts[1]; $saveX3
+=1; } 
  elsif ($parts[0] eq 'BEGIN' && $parts[2] eq 'TAG' ){ 
        #print $savetoX3."\n" if ($savetoX3) ; 
        $savetoX3=''; 
        $saveX3=0; 
       } 
  elsif ($saveX3) { $savetoX3.=' '.$line; } 
  
  
  
  
  }
print "X1: ".$savetoX1."\n" if ($savetoX1) ; 
print "X2: ".$savetoX2."\n" if ($savetoX2) ; 
print "X3: ".$savetoX3."\n" if ($savetoX3) ;
