Re: Basics of XSLT

Thank you.Can anyone explain XPath more?

I was advised to use "XML::LibXSLT::xpath_to_string" in the following code.

 my $parser = XML::LibXML->new();
 my $xslt = XML::LibXSLT->new();

 my $source = $parser->parse_file($xmlfile);
 my $style_doc = $parser->parse_file($xslfile);

 my $stylesheet = $xslt->parse_stylesheet($style_doc);

 my $results = $stylesheet->transform($source,
XML::LibXSLT::xpath_to_string(args => "$in{'args'}",value => "$value",
cnt => "1",);

 print $stylesheet->output_string($results);
