To overcome the two problems here (client side loading the template and ending browser support) you could throw in php in the mix and have a wonderful solution for templating with bullet proof standards: // XML $xml_doc = new DOMDocument(); $xml_doc->load("file1.xml"); // XSL $xsl_doc = new DOMDocument(); $xsl_doc->load("file.xsl"); // Proc $proc = new XSLTProcessor(); $proc->importStylesheet($xsl_doc); $newdom = $proc->transformToDoc($xml_doc); // Output print $newdom->saveXML(); XSLT lacks functionality? No problem, use php functions in xslt: https://www.php.net/manual/en/class.xsltprocessor.php https://www.php.net/manual/en/class.xsltprocessor.php
