Code:
#!/usr/bin/env perl

use strict;
use warnings;

use XML::Fast;
use Template;

my $xml = <<'XML';
 <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)

That's because Windows does not recognize the pdflatex program.

Hi, I generated latex template using perl,and complied with MikTeX, its genarating pdf. I written script like this
Code:
#!/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>   
</student>
<student>
      <number>23</number>
      <education>ph.d.</education>
      <specialization>physics </specialization>
     <address>
         <house_number="12"/>
         <street name="xxxx"/>
           <kadapa/>
      </address>
</student>
XML
my $xml_hash = xml2hash $xml;

my $template = Template->new();

my $filename = 'output.tex';


$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 and his address is[%address%][%house_number%][%street name%].
[% END %]

\end{document}

when I run it its generating pdf with like this
Code:
student 24 is a computers student and his address is HASH(0x274b27c)
student 23 is a computers student and his address is HASH(0x274b27c)

but I need to print address also but it printing hash not address how to get the address element content also like this
Code:
student 24 is a computers student and his address is 
 house_number="128";
 street name="xxxx";
 proddutoor.
student 23 is a computers student and his address is 
 house_number="12";
 street name="xxxx";
 kadapa.

what should I need to change to print like this in pdf.

2) I have one more question if I am giving input like this XML data its excuting what can I do if I have one file with data same as like this,for example more number of students data in my file.

The gibberish is not the hash; you haven't deferenced the reference.
Not sure what your 2nd question is.
