Answer 1

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(f);
Element root = doc.getDocumentElement();
NodeList nodeList = doc.getElementsByTagName("player");
for (int i = 0; i < nodeList.getLength(); i++) {
  Node node = nodeList.item(i);
  // do your stuff
}

but I'd rather suggest to use XPath

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(<uri_as_string>);
XPathFactory xPathfactory = XPathFactory.newInstance();
XPath xpath = xPathfactory.newXPath();
XPathExpression expr = xpath.compile("/GameWorld/player");
NodeList nl = (NodeList) expr.evaluate(doc, XPathConstants.NODESET);
