So, the design goes like this, the script should process the last but one file which is not a tmp file ( that one that ends with tmp )

so once that is being processed, another tmp file would be created and the script should poll for it and once done it should start processing that

Please correct me if am wrong !

something like might help but it is made such a way to run ever
Code:
open(OUTPUT, ">>", "output.txt");

while (1) {

#Make it as ever running process

$file = `ls -lrt | awk '/SMSCDR/ { before = curr; curr = $9 }END{ print before }'`; 

#select the file which is last but one

next if ( $file =~ /tmp/ );

#if its the 'tmp' file dumper process is still active so don't process it else continue processing

open (FILE, "<", $file) or die  "Unable to open file $file <$!> \n";

#open the file and start processing

while(<FILE>) {
chomp;
my @arr = split(/></);
foreach (@arr) {
if( /xml version/ ) {
$c++;
print OUTPUT "\n";
}
if( />/ && /</ ) {
if( $c == 1 ) {
s/(.*)>(.*)<.*$/1|2/;
my($tmp1, $tmp2) = split(/|/);
$data .= (" " . $tmp2);
printf OUTPUT "%s ", $tmp1;
}
else {
s/(.*)>(.*)<.*$/2/;
printf OUTPUT "%s ", $_;
}
}
}
print OUTPUT "\n";
print OUTPUT "$data\n" if( /xml version/i );
}

close (FILE);

#continue with while loop, by this time dumper process might have completed and next file ready for processing
}

close(OUTPUT);

exit 0;

pfsinhdrgen(1)						      General Commands Manual						    pfsinhdrgen(1)

NAME

       pfsinhdrgen - Create a pfs stream with different exposures defined by hdrgen script.

SYNOPSIS

       pfsinhdrgen <sample.hdrgen>

DESCRIPTION

       This  program  reads  files  defined  in  given	hdrgen script and outputs them in a PFS stream. Each frame has a tag BV with corresponding
       brightness value (APEX standard). Larger BV corresponds to less exposure (darker image), necessary to capture a bright scene.

       The generated PFS stream is to be used with photo-metric calibration software and with generators of HDR images.

       HDRGEN script file is a plain text file in  which  each	line  contains:  <path_to_an_image>  <inverse_of_exposure_time_in_seconds>  <aper-
       ture_size> <iso_speed> 0

       In  most  cases	it  is	convenient to use the jpeg2hdrgen program to create such a file automatically. In case it could not parse the exif
       information from jpeg files, it is necessary to create this file by hand. Below are the sample contents of such file:

       <--- cut here: sample.hdrgen /var/tmp/images/img08.jpg 4 2.8 100 0 /var/tmp/images/img09.jpg 58.8235 2.8  100  0  /var/tmp/images/img10.jpg
       76.9231 2.8 100 0 /var/tmp/images/img11.jpg 322.581 2.8 100 0 /var/tmp/images/img12.jpg 400 2.8 100 0 <--- cut here: sample.hdrgen

EXAMPLES

       pfsinhdrgen sample.hdrgen | pfsview

	      View exposures defined in sample.hdrgen script.
