Re^3: How to return two and more values by parsing XML with XML::Rules?

I was referring to the yaml, and FWIW, ysh doesn't like that YAML, which I assume is supposed to be

ysh > ---
yaml> Outpatient_Services:
yaml>   Outpatient_Service:
yaml>     - AM11: 1
yaml>     - AM07: 1
yaml>     - AM04: 1
yaml> ...
$VAR1 = {
  'Outpatient_Services' => {
    'Outpatient_Service' => [
      {
        'AM11' => '1'
      },
      {
        'AM07' => '1'
      },
      {
        'AM04' => '1'
      }
    ]
  }
};
[download]

This is what I came up with, which took waaay too long, the rules are hard to remember

#!/usr/bin/perl --
use strict; use warnings;
use XML::Rules;
use Data::Dump qw/ dd /;

my $ta = XML::Rules->new(
    qw/ stripspaces 8 /,
    rules => {
'Outpatient_Services' =>  'no content',
  'Outpatient_Service' => 'as array no content',
#~     'Outpatient_Clinic' => 'content by AM_Key',
    'Outpatient_Clinic' => sub {
#~ $rule->( $tag_name, \%attrs, \@context, \@parent_data, $parser)
#~ my ($tagname, $attrHash, $contexArray, $parentDataArray, $parser) =
+ @_;
        my $amk = $_[1]->{AM_Key} ;
        return unless $amk;
        { $amk => 1 };
    },
#~         _default => sub { $_[0] => $_[1]->{_content} },
        _default => 'content',
        'Outpatient_Clinic_Special' => undef,
    },

);

my $ref = $ta->parsefile( 'pm1002448.xml' );
dd $ref;
use YAML(); print YAML::Dump( $ref);
__END__
{
  Outpatient_Services => {
    Outpatient_Service => [
      { AM01 => 1 },
      { AM01 => 1 },
      { AM02 => 1 },
      {},
      { AM04 => 1 },
      {},
    ],
  },
}
---
Outpatient_Services:
  Outpatient_Service:
    - AM01: 1
    - AM01: 1
    - AM02: 1
    - {}

Thank you very much! I noticed now ( but somewhat late :-) ) that your point was yaml output. I have corrected the output presentation in the original post and in the reply to your post. My main problem however ist that I need to represent the LK-Keys at the same hierarchy level as the AM-Keys. That is, I do need the Outpatient_Clinic_Special infos. Thank you again for your time I will try to build on your code.	[reply]

My main problem however ist that I need to represent the LK-Keys at the same hierarchy level as the AM-Keys. Your updated output doesn't show that. Only AM04 is found in your sample data. Anyway, see Re: How to return two and more values by parsing XML with XML::Rules?, save the key callback `my $amlk = sub { print $_->xpath, "\n"; push @amk, $_->trimmed_text; };` [download] Then register some twig_handlers `'AM_Key' => $amlk, 'LK_Key' => $amlk,` [download]	[reply] [d/l] [select]

Your updated output doesn't show that. I am getting old ... I used your code with XML::Twig for LK_Keys Re^2: How to return two and more values by parsing XML with XML::Rules? but your recent proposal with the callback is of course much better and also shows that I have to learn much much more ... It is furthermore still the question for me what module should I use as a main option by parsing the data related xml-files? Thank you very much again!	[reply]
