// An XMLNode is how XML is represented in Server-Side JavaScript. Like JSON 
// ObjectNodes, XMLNodes are immutable. Use NodeBuilder to construct XML or 
// literal JavaScript objects to build JSON nodes in JavaScript. 
xml instanceof XMLNode && xml instanceof Node && xml instanceof Value; // true

for (var element of xml.xpath('//ex:p', {'ex': 'http://example.com'})) {
  // All XMLNode instances support a read-only w3c DOM interface
  var text = element.textContent;
  // typeof text === 'string'
  var children = element.childNodes; 
  // children instanceof NodeList && children.length === 3

  // …as well as any node function, i.e. any XDM function that takes a node as the first argument
  // For example, to validate against a schema:
  //   element.validate();
  // is equivalent to 
  //   xdmp.validate(element);
