The workflow:

The Cloupia Script:

importPackage(org.w3c.dom);

importPackage(javax.xml.parsers);

importPackage(java.io);

importPackage(java.lang);

importPackage(java.util);

var factory = DocumentBuilderFactory.newInstance();

var builder = factory.newDocumentBuilder();

var xmlStringBuilder = new StringBuilder();

xmlStringBuilder.append("<?xml version='1.0'?><Cars><Car Type='System.String'>Opel</Car><Car Type='System.String'>Mercedes</Car><Car Type='System.String'>Porsche</Car></Cars>");

var input =  new ByteArrayInputStream( xmlStringBuilder.toString().getBytes('UTF-8') );

var doc = builder.parse(input);

doc.getDocumentElement().normalize();

var nList = doc.getElementsByTagName("Car");

logger.addInfo("Root element :" + doc.getDocumentElement().getNodeName());

logger.addInfo("nList length: " +nList.getLength() );

for (var i = 0; i < nList.getLength(); i++) {

    var nNode = nList.item(i);

    logger.addInfo("\nCurrent Element : " + nNode.getNodeName());

   // logger.addInfo("\nNodeType : " + nNode.getNodeType());

    //logger.addInfo("typeof nNode: "+typeof nNode);

    var value = nNode.getTextContent();

        logger.addInfo("Object: " + value );

}
