How do I create an XML template in Perl?

The XML file I need to create is like

<file>
     <state>$state</state>
     <timestamp>$time</timestamp>
     <location>$location</location>
          ....
</file>

I don't want to use multiple prints to create the required XML file, and I am expecting a template that defines the structure and format of the XML.

Then, when you create the XML file, I just need to provide the actual values ​​for the variables in the template, and write the specified template to the file I just created once, just once.

use HTML::Template

.

#!/usr/bin/perl

use strict;
use warnings;

use HTML::Template;

my $template_text = <<EO_TMPL;
<TMPL_LOOP FILES>
<file>
     <state><TMPL_VAR STATE></state>
     <timestamp><TMPL_VAR TIME></timestamp>
     <location><TMPL_VAR LOCATION></location>
</file>
</TMPL_LOOP>
EO_TMPL

my $tmpl = HTML::Template->new( scalarref => \$template_text );

$tmpl->param(
    FILES => [
    { state => 'one', time => 'two', location => 'three' },
    { state => 'alpha', time => 'beta', location => 'gamma' },
]);

print $tmpl->output;


Output:

<file>
     <state>one</state>
     <timestamp>two</timestamp>
     <location>three</location>
</file>

<file>
     <state>alpha</state>
     <timestamp>beta</timestamp>
     <location>gamma</location>
</file>

cpan

contains several XML modules that you could use.

My suggestion is that you start with XML::Simple

orXML::API
