Question

Hi how can I read this information using template toolkit

 $var1= {  
  'STC'=>[
     {
        'gym'=>{
              'hyd'=>{
                   'com'=>[
                        'dr'=>'1', 
                         'typ'=>'z',
                          'bemo'=>{
                               'bm'=>'1',
                                'typ'=>'x',
                                'col'=>'red'
                                 }
                               } 
                            {
                          'dr'=>'12', 
                         'typ'=>'a',
                          'bemo'=>{
                               'bm'=>'25',
                                'typ'=>'p',
                                'col'=>'red'
                                 }
                            } 
                         {
                          'dr'=>'23', 
                         'typ'=>'k',
                          'bemo'=>{
                               'bm'=>'22',
                                'typ'=>'w',
                                'col'=>'blue'
                                 }

                                 }
                            } 

                          }
                       }

I am not able to get this type of complex data , Remaining everything I solved and I am getting output as I want but this problem suffers me.please help me.

ok so you have some data, what do you expect it to look like? At the risk of sounding snarky, you could simply open in a text editor and print pdf or save as rtf. Clearly this isn’t what you mean.

You need to format the data somehow. Then the conversion will simply be the application of that your data to that format.

As I mention here, you could make a LaTeX template and fill it in with your data and Template::Toolkit and compile using a LaTeX compiler. This would get you a PDF.

#!/usr/bin/env perl

use strict;
use warnings;

use XML::Fast;
use Template;

my $xml = <<'XML';
 <student>
      <number>24</number>
      <education>bachelors</education>
      <specialization>computers </specialization>
     -<address>
         <house_number="128"/>
         <street name="xxxx"/>
           <proddutoor/>
      <address/>
     -<details>
          <name="clar"/>
          <age="20"/>
         <sex="m"/>
       </details>
</student>
 <student>
      <number>23</number>
      <education>ph.d.</education>
      <specialization>physics </specialization>
     -<address>
         <house_number="128"/>
         <street name="xxxx"/>
           <proddutoor/>
      <address/>
     -<details>
          <name="joel"/>
          <age="20"/>
         <sex="m"/>
       </details>
</student>
XML
my $xml_hash = xml2hash $xml;

my $template = Template->new();

my $filename = 'output.tex';

#I think the following is a holdover from a previous version
#as I cannot check right now, I will leave as a comment:
#open my $fh, '>', $filename;

$template->process(\*DATA, $xml_hash, $filename)
    || die "Template process failed: ", $template->error(), "\n";

system( "pdflatex $filename" );

__DATA__
\documentclass{article}

\title{Roster}
\author{pavani}

\begin{document}
\maketitle

[% FOREACH st IN student %]
Student [% st.number %] is a [% st.specialization %] [% st.degree %] student.

[% END %]

\end{document}

N.B. XML::Fast even does surprisingly well against your poorly formatted XML 🙂
