Question

How can I return the entire xml tag using xml::twig and save it to array:

for example :

my @array=();
my $twig = XML::Twig->new(
twig_handlers => {
'data'=> sub {push @array, $_->xml_string;}

});

This code return all the nested tags but without the tag itself and its properties is there an option to return the entire tag using xml::twig and save it to varaible ?

Answer 1

Use XML::Twigs method sprint instead of xml_string. The docs say that:

xml_string @optional_options

Equivalent to $elt->sprint( 1), returns the string for the entire element, excluding the element's tags (but nested element tags are present)

A search for that sprint function yields:

sprint

Return the text of the whole document associated with the twig. To be used only AFTER the parse.

Thus, you can do the following:

use strict;
use warnings;
use Data::Dumper;
use XML::Twig;

my @array=();
my $twig = XML::Twig->new(
twig_handlers => {
  'data'=> sub {push @array, $_->sprint;}
});

$twig->parse(qq~
  <xml>
        <data id="foo">
      <deep>
            <deeper>the deepest</deeper>
      </deep>
    </data>
  </xml>
~);

print Dumper \@array;

Which prints:

$VAR1 = [
          '<data id="foo"><deep><deeper>the deepest</deeper></deep></data>'
        ];
