This is my first post, so I hope I don't mess anything up.

I am creating a module that deals with a specific kind of xml called ettx. The object it creates is supposed to hold two hashes for comparison later. This is the code so far:

#!/usr/bin/perl -l
package ETTX;
use strict;
use warnings;
use XML::Simple;
use Data::Dumper;

sub load(;$){#file name
    my $class = shift;
    my $self;
    if(@_ == 1){
        my $xml = XML::Simple->new();
        $self  = { 
            ettx => $xml->XMLin(shift),    #for main file
            template => {},
        };
    }
    else{
        $self = {
            ettx => {},
            template => {},
        }
    }
    bless $self, $class;
    return $self;
};

sub loadEttx($){
    my $self = shift;
    my $xml = XML::Simple->new();
    $self=>{ettx} = $xml->XMLin(shift);
}

sub loadTemplate($){
    my $self = shift;
    my $xml = XML::Simple->new();
    $self=>{template} = $xml->XMLin(shift);
}
1;

However, I'm getting a compile time error which says:

Can't modify anonymous hash ({}) in scalar assignment at C:\Texts\Programs\ETTX.pm line 31, near "};"

Line 31 being the one that says "$self=>{ettx} = {};"

I can't find my error anywhere. Can anyone spot it?

Thanks! ---Nathan
