Generating random XML documents

I'm trying to generate a fresh XML file using Perl XML::Mini::Document. It's working fine, but I don't know whether it's the right way to do it. Performance is the problem for me; it takes more time when the when record count increases.

Is there any other module better doing than this one in performance and easier way?

#!/usr/bin/perl -w

use warnings;
use XML::Mini::Document;

my $outfile = "D:/Test.xml";

my $nSequence = 1000;
my $sRandom_Name = "";
my $sRandom_Desc = "";
my $newDoc = XML::Mini::Document->new();
my $newDocRoot = $newDoc->getRoot();
my $xmlHeader = $newDocRoot->header('xml');
$xmlHeader->attribute('version', '1.0');
$xmlHeader->attribute('encoding', 'UTF-8');

my $records= $newDocRoot->createChild('records');

for(0..9) {

   for(1..6) { 
      $sRandom_Name = $sRandom_Name.(chr(int(rand(25) + 65)));
   }
   for(1..15) { 
      $sRandom_Desc = $sRandom_Desc.(chr(int(rand(25) + 97)));
   }

   my $record = $records->createChild('record');

   $record->createChild('ID')->text($nSequence=$nSequence+1);
   $record->createChild('Name')->text($sRandom_Name);
   $record->createChild('Desc')->text($sRandom_Desc);

   print $newDoc->toFile($outfile);
}

My output should look like this one:




1001
ASDSDF
ASDFsdsdfcwefSC


1002
KDFNND
WEFsdssccwefSC


1003
PORJDX
XceFsdsdfcASmsd

Yes, that's pretty good. It's essential to include use strict at the top of every Perl program you write, and use warnings is preferable to -w on the command line. You should also avoid capital letters in identifiers for lexical variables, as they are reserved for use in global identifiers such as package names

I would write something more Perlish like this

#!/usr/bin/perl

use strict;
use warnings;

use XML::Mini::Document;

use constant OUTFILE => 'D:/Test.xml';

sub rand_letter { chr(ord('A') + rand(26)) }

my $new_doc = XML::Mini::Document->new;
my $root    = $new_doc->getRoot;
my $header  = $root->header('xml');
$header->attribute(version  => '1.0');
$header->attribute(encoding => 'UTF-8');

my $records= $root->createChild('records');

my $sequence = 1000;

for ( 0..9 ) {

    my $record = $records->createChild('record');

    my ($random_name, $random_desc);
    $random_name .= rand_letter for 1 .. 6;
    $random_desc .= rand_letter for 1 .. 15;

    $record->createChild(ID   => ++$sequence);
    $record->createChild(Name => $random_name);
    $record->createChild(Desc => $random_desc);
}

open my $fh, '>', OUTFILE or die $!;
select $fh;
print $new_doc->toString;
