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{document}

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

xml::libxml::attributehash

XML::LibXML::AttributeHash(3)				User Contributed Perl Documentation			     XML::LibXML::AttributeHash(3)

NAME

       XML::LibXML::AttributeHash - tie an XML::LibXML::Element to a hash to access its attributes

SYNOPSIS

	tie my %hash, 'XML::LibXML::AttributeHash', $element;
	$hash{'href'} = 'http://example.com/';
	print $element->getAttribute('href') . "
";

DESCRIPTION

       This class allows an element's attributes to be accessed as if they were a plain old Perl hash. Attribute names become hash keys.
       Namespaced attributes are keyed using Clark notation.

	my $XLINK = 'http://www.w3.org/1999/xlink';
	tie my %hash, 'XML::LibXML::AttributeHash', $element;
	$hash{"{$XLINK}href"} = 'http://localhost/';
	print $element->getAttributeNS($XLINK, 'href') . "
";

       There is rarely any need to use XML::LibXML::AttributeHash directly. In general, it is possible to take advantage of XML::LibXML::Element's
       overloading. The example in the SYNOPSIS could have been written:

	$element->{'href'} = 'http://example.com/';
	print $element->getAttribute('href') . "
";

       The tie interface allows the passing of additional arguments to XML::LibXML::AttributeHash:

	tie my %hash, 'XML::LibXML::AttributeHash', $element, %args;

       Currently only one argument is supported, the boolean "weaken" which (if true) indicates that the tied object's reference to the element
       should be a weak reference. This is used by XML::LibXML::Element's overloading. The "weaken" argument is ignored if you don't have a
       working Scalar::Util::weaken.
