Here is the updated code,

the reason why it didn't work in the first phase is that, input format was different, there were no 'line feeds' in the sample file provided.

Now it should work!

Let us know how it proceeds!

Code:
#! /opt/third-party/bin/perl

my $c = 0;

open(FILE, "<", "sample.txt");

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

close(FILE);

exit 0

Histogram(3)						User Contributed Perl Documentation					      Histogram(3)

NAME

       PDL::RandVar::Histogram -- Arbitary distribution random variables

VERSION

	 Current version is 1.0

SYNOPSIS

	 use PDL::RandVar::Histogram
	 $m = new PDL::RandVar::Histogram($dist);

DESCRIPTION

       Histogram random variables are useful for generating distributions to match arbitrary vector (N-D) data.  On initialization, you feed in a
       clumped array whose value is proportional to the probability of landing in each bin.   You get back values of indices into the original
       vector.	If you ask for it, you can get subsampling in the mantissa of each index.
