Hi,
I have small doubts in the above module, i am reading "perlmod " i understand something. i am asking you,
can i use like this : package xmlhashtable as a module name.
can i use require function to call this module in my main section.
Code:
require My::XML::ashash

and also i am using strawberry Perl latest version so i need to install any anything to execute this program.
can you explain whats going with this comments.
Code:
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};

why we are opening file in this module ,we can directly open in the main function.
finally is there any another easy way to create module. i started to read your suggested tutorials.

thank you very much for reply.

regards,
veerubiji.

        or die ("unable to open file");
    my %nums;
    while ($reader->nextElement( 'Data' ) ) {
 
        my $des = $reader->readOuterXml();
 
        $reader->nextElement( 'Number' ); 
        my $desnode = $reader->readInnerXml();

}
 
1;
