Hi I have xml file from that using XML::LiBXML I extracted and stored in a hash. after that using template I am generating pdf file. I written script like this

    #!/usr/bin/perl
    use warnings;
    use strict;
        use Data::Dumper;
        use Template;
    use XML::LibXML::Reader;

    my $file;

    open( $file, 'DTC_Specification_transformed.xml');

    my $reader = XML::LibXML::Reader->new( IO => $file ) or die ("unab
+le to open    
        file");
         my %nums;
     my $num=0;
        while ($reader->nextElement( 'DATA' ) ) {
          $num=$num+1;
           $reader->nextElement( 'Test' ); 
    my $information = $reader->readOuterXml();
     $reader->nextElement( 'testinfo' ); 
    my $testnumber = $reader->readOuterXml(); 
    $nums{$infortion}= $testnumber;
        }
         print %nums;
         close($file);

     my $template = Template->new();
     my $filename = 'output.tex';
     $template->process(\*DATA, %nums, $filename)
    || die "Template process failed: ", $template->error(), "\n";

     system( "pdflatex $filename" );

          __DATA__
         \documentclass{article}

      \title{testinformation of each data}
       \author{michel\\ 
     \begin{document}
       \maketitle
        [% FOREACH st IN test %]
       DTC number:[% st.test %] \\
      test information[% st.testinfo.temperature%] 
        [%st.testinfo.humidity %]
        [% END %]
       \end{document}

but it generating pdf file without any information.I tried to print hash %nums it printing like this

    $var1={
            <test>1<test>'=>'<testinfo>
                              <temperature="23"/>
                               <humidity="80"/>
                                </testinfo>
             <test>2<test>'=>'<testinfo>
                              <temperature="27"/>
                               <humidity="75"/>
                                </testinfo>........so many tests
                }

I need to print like this in pdf

    testnumber= 1,
      testinfo: temperature= "23",
                  humidity="80"    
    testnumber= 2,
       testinfo: temperature= "27",
                   humidity="75"
