Hello snehit.ar,

I run your updated code and sample of data and I got:

$ perl test.pl

no element found at line 12, column 0, byte 209:
  </application>
  <application_list>

^
 at /home/tinyos/perl5/lib/perl5/x86_64-linux/XML/Parser.pm line 187.

Simply modify your xml file to:

<application_list>
  <application id = "111">
    <contacts>
      <technical>
    <name>John</name>
    <name>Ram</name>
    <name>Rahim</name>
      </technical>
    </contacts>
  </application>
</application_list>

And re run your script:

#!/usr/bin/perl
use strict;
use warnings;
use XML::XPath;
use feature 'say';

my $appxml = 'ApplicationList.xml';
my $appxp = XML::XPath->new(filename => $appxml);
my $xp = $appxp->findnodes('//application_list/application/');
my %appid;
my @apprecords;

foreach my $appnodeset ($xp->get_nodelist) {
    my $id = $appnodeset->find('@id')->string_value;
    $id =~ s/^\s+|\s+$//g;

    foreach my $spltname (
    $appxp->findnodes('./contacts/technical', $appnodeset) )  {
    my $name = join ",",
    map $_->string_value,
    $spltname->findnodes('.//name'); # add this as suggested by chorob
+a
    $appid{$id} = $name;
    say $name;
    }
}

__END__
