Re: XML::Twig and file encoding

... somethings wrong ...

Great :) prove it

Finish this program, post it, and post the output

#!/usr/bin/perl --
use Path::Tiny qw/ path /;
use Data::Dump qw/ dd /;

my $infile  = 'three-lines-unicode.xml';
my $outfile = 'three-lines-uniWHAT.xml';
dd( path( $infile )->slurp_utf8 );
getTwiggy( $infile , $outfile );
dd( path( $outfile )->slurp_raw );
sub getTwiggy { ## minimal demo of Twig not what you want

}
__END__

But you probably don't want to use http://xmltwig.org/xmltwig/twig_dev.html#METHODS_XML_Twig_new_keep_encoding This is a (slightly?) evil option: if the XML document is not UTF-8 encoded

xmltwig.org keep-encoding site:xmltwig.org keep-encoding

getting an error, maybe I coded something wrong here. (Running on Win7 BTW - should've mentioned.)

Error open (<:unix) on 'twiggy-WHAT.xml': No such file or directory at C:\working\scripts\ifx-make-conrefs\twiggy.pl line 9.

my code

#!/usr/bin/perl --
use Path::Tiny qw/ path /;
use Data::Dump qw/ dd /;

my $infile  = 'twiggy-test.xml';
my $outfile = 'twiggy-WHAT.xml';
dd( path( $infile )->slurp_utf8 );
getTwiggy( $infile , $outfile );
dd( path( $outfile )->slurp_raw );
sub getTwiggy { ## minimal demo of Twig not what you want

}
__END__

I do get my XML printed to screen.

thanks for looking at this.

You missed the point :) You didn't finish the program :) you did not complete sub getTwiggy which is supposed to create $outfile

How else would I know what you're doing with XML::Twig and what goes wrong?

[slugger415]

ok sorry, brain cramp!

#!/usr/bin/perl --
use Path::Tiny qw/ path /;
use Data::Dump qw/ dd /;
use XML::Twig;

my $infile  = 'twiggy-test.xml';
my $outfile = 'twiggy-WHAT.xml';
dd( path( $infile )->slurp_utf8 );
getTwiggy( $infile , $outfile );
dd( path( $outfile )->slurp_raw );
sub getTwiggy { 
 
 # set up the XML parser:
 my $twig= XML::Twig->new( 
   comments => 'keep',
 #  keep_encoding => 1,
   keep_spaces=> 1,
   twig_handlers => { li => sub_ix_strings($infile),
                 
               },
 );
 
 $twig->parsefile($infile);

   print "  Saving $outfile...\n";
   open(NEW,">$outfile") || die("cannot open file $outfile for writing
+.\n");
   $twig->flush( \*NEW);
   close(NEW);

}

sub sub_ix_strings {
  my($file) = @_;
  return sub {    
   my($twig,$elt) = @_;
   $elt->set_att('test',"hello");
  }
}
__END__

OUTPUT (looks the same, but file is now ANSI not UTF-8):

<?xml version="1.0" encoding="UTF-8"?>
<reference id="ids_excal_142" xml:lang="en-us">
<title>The ISO character set</title>
<refbody>
<section><p>Each ISO character has its own value, except that lowercas
+e
characters are translated to uppercase. Two characters that have no
uppercase equivalent are: <ul>
<li test="hello">German small sharp s (ß - 0xDF)</li>
<li test="hello">Lowercase y diaeresis/umlaut (ÿ - 0xFF)</li>
</ul></p></section>
</refbody>
</reference>

So the output looks ok in my text editor (TextPad) but when I open it in an XML editor (Arbortext or Oxygen) the special characters don't display correctly.

Thanks! Scott
