Hi,

I am trying to use a script that uses XML::Twig to modify specific tags in xml docs(I got the suggestion to use XML::Twig from another monk btw). The script does what I want, but in addition to updating the xml files, it also spits out a bunch of output as a single line:

<merchant>BOB</merchant><merchant>Jane</merchant></testProduct><mercha
+nt>BOB</merchant><merchant>Jane</merchant></testProduct><merchant>BOB
+</merchant><merchant>Jane</merchant></testProduct><merchant>BOB</merc
+hant><merchant>Jane</merchant></testProduct><merchant>BOB</merchant><
+merchant>Jane</merchant></testProduct><merchant>BOB</merchant><mercha
+nt>Jane</merchant></testProduct><merchant>BOB</merchant><merchant>Jan
+e</merchant></testProduct><merchant>BOB</merchant><merchant>Jane</mer
+chant></testProduct>

I'm not sure why that is -- I thought the script was writing directly to the xml files I was editing? Anyway, if there are any tips on modifying my code to remove the stdout output, or tips on prettifying the data, I'd appreciate it. Here is my script:

#!/usr/bin/perl

use strict;
use warnings;
use File::Find;
use XML::Twig;

@ARGV = ('.') unless @ARGV;

my $dir = shift @ARGV;

find(\&edits, $dir);

sub edits() {

    my $seen = 0;
    my $file = $_;

    if ($file eq 'data.xml') {
        my $orig = 'data.xml';
        use autodie 1.999;
        use POSIX 'strftime';

        my $back = $orig . strftime( '-%Y-%m-%d', localtime );
        rename $orig, $back;

        open my $newfh, '>', $orig;

        my $t = XML::Twig->new(
                               twig_roots => {
                                   'merchant' => sub {
                                       my ( $t, $value ) = @_;
                                       {
                                           my $ra = $value->text;
                                           $ra =~ s/_/ /g;
                                           $value->set_text($ra);
                                       }
                                       $value->print($newfh);
                                   },
                               },
                               twig_print_outside_roots => $newfh,
                               );
        $t->parsefile($back);
        $t->flush;    #don't forget
        undef $t;     #
        close $newfh;

    }

}
