Ahh, now I get you, your module would look a bit like this...

Code:
#!/usr/bin/perl

package  My::XML::AsHash; # or whatever you want to call the package (remember to have the appropriate directory structure)

use warnings; 
use strict; 
use XML::LibXML::Reader; 
my $DEBUG=1; 
sub new{
   my($proto,%args)=@_;
   my $class= ref($proto)||proto; #Make inheritable
   my $self;    open( $self->{file}, '<', $args{'file'});
   my $reader = XML::LibXML::Reader->new( IO => $self->{file} ) 
      or die ("unable to open file");    # my $self->{nums};    
   while ($reader->nextElement( 'Data' ) ) {
        my $des = $reader->readOuterXml();
        $reader->nextElement( 'Number' );
         my $desnode = $reader->readInnerXml();
         $self->{nums}->{$desnode}= $des;
        print( " NUMBER: $desnode\n" ) if $DEBUG;
        print( " Datainfo: $des\n" ) if $DEBUG;
   }
   bless($self,$class);
}
exit 1;

It would be saved in for example /home/veerubiji/perl_libs/My/XML/AsHash.pm and would be called as follows
Code:
#!/usr/bin/perl
push @INC '/home/veerubiji/perl_libs/';
use My::XML::AsHash;
my $hash_of_xml=My::XML::AsHash->new(file=>'formal.xml');
for my $desnode (keys %{$hash_of_xml->{nums}}){
    print "$hash_of_xml->{nums}->{$desnode} is the value associated with $desnode\n";
}

This is a very rough and ready module however and I would STRONGLY recommend reading through perldoc perlboot and perldoc perltoot. A real world module should have an associated test suite, would provide accessors to the nums hash rather than exposing them directly, would have a perldoc section so that others could re-use your code and finally would be packaged so that you could install it on any of your users workstationsh2xs -XA -n My::XML::AsHash.
For someone who is at the beginning of their Perl coding you've jumped into the deep end, Have fun!

xml::libxml::comment

XML::LibXML::Comment(3) 				User Contributed Perl Documentation				   XML::LibXML::Comment(3)

NAME

       XML::LibXML::Comment - XML::LibXML Comment Class

SYNOPSIS

	 use XML::LibXML;
	 # Only methods specific to Comment nodes are listed here,
	 # see XML::LibXML::Node manpage for other methods

	 $node = XML::LibXML::Comment->new( $content );

DESCRIPTION

       This class provides all functions of XML::LibXML::Text, but for comment nodes. This can be done, since only the output of the node types is
       different, but not the data structure. :-)

METHODS

       The class inherits from XML::LibXML::Node. The documentation for Inherited methods is not listed here.

       Many functions listed here are extensively documented in the DOM Level 3 specification (<http://www.w3.org/TR/DOM-Level-3-Core/>). Please
       refer to the specification for extensive documentation.

       new
	     $node = XML::LibXML::Comment->new( $content );

	   The constructor is the only provided function for this package. It is required, because libxml2 treats text nodes and comment nodes
	   slightly differently.
