You are using an external proprietary program. I checked the ETAX Documentation, and I couldn't find any usage documentation. I did find chrBrk which is supposed to be a list of break characters. Again, no documentation for it. Here's the way that I tried it:

#!/usr/bin/perl

use strict;
use Data::Dumper;
use XML::Simple qw(:strict);

my $xs = XML::Simple->new();

my $blah = $xs->XMLin('/root/Desktop/txt.xml',
            ForceArray => 1,
            KeyAttr => 1);
binmode STDOUT, ':utf8';            
print Dumper($blah);
