Dear Monks,
I want to convert one xml file to another. I am using XML::Twig, version 3.23 and perl 5.8.3.
The input file contains HTML-Entities (ie & in the example below) in some text elements.
I do not want them to be changed, but on flushing the parent element, they are converted to the representing character (&), yielding an invalid xml file.
So the question is how to prevent XML::Twig from converting the entities.
Any hints?
Thanks in advance,
Martin

The script: 
#!/usr/bin/perl

use strict;
use File::Basename;
use XML::Twig;

binmode(STDOUT, ":utf8");

my ($inFile)=@ARGV;

unless (open ("INFILE", "<:utf8", "$inFile")){
    die "$inFile: No such file or directory.";
}

my $t= XML::Twig->new( twig_handlers => 
                       {   "identifier" => \&section,
                           "record" => sub { $_[0]->flush; }
                       },
                       );
$t->set_pretty_print("nice");
$t->set_keep_encoding;
$t->parsefile($inFile);

exit 0;

sub section { 
    my( $t, $elt)= @_;
    my $elt_txt = $elt->text;
    my $new_elt;

    if ($elt_txt =~ /^http:\/\/arxiv.org/) {
        $new_elt = XML::Twig::Elt->new( $elt->tag . ".url" => $elt_txt
+);
    } elsif ( $elt_txt =~ /^doi:/ ) {
        $new_elt = XML::Twig::Elt->new( $elt->tag . '.doi' => $elt_txt
+);
    }
    $elt->replace_with($new_elt) if $new_elt;
}
