If you want to query an XML file, at first sight, you must use a mapping. But it's like using a tank to kill a mouse !
Fortunately, we can do better with scripting.
The following example shows how to open an XML file and how to query it with an XPath expression :

factory = javax.xml.parsers.DocumentBuilderFactory.newInstance(); 
builder = factory.newDocumentBuilder(); 
doc = builder.parse("%x{md:paramValue($this,'XML_FILE_NAME')}x%"); 
xpathFactory = javax.xml.xpath.XPathFactory.newInstance(); 
xpath = xpathFactory.newXPath(); 
expr = xpath.compile("%x{md:paramValue($this,'XPATH_EXPRESSION')}x%"); 
result = expr.evaluate(doc,javax.xml.xpath.XPathConstants.STRING);
