java读取xml(二)

关于xml和上一篇文章一样

public void printNodeInfo(Node node) {System.out.println(node.getNodeName() + ":" + node.getNodeValue());}public void printNode(Node node) {switch (node.getNodeType()) {case Node.PROCESSING_INSTRUCTION_NODE:System.out.println("--------------PI start---------------------");printNodeInfo(node);System.out.println("--------------PI end---------------------");break;case Node.ELEMENT_NODE:System.out.println("--------------element start---------------------");printNodeInfo(node);NamedNodeMap attrs = node.getAttributes();for (int i = 0; i < attrs.getLength(); i++) {System.out.println("-------------------attr start--------------------");System.out.println(attrs.item(i));System.out.println("-------------------attr end--------------------");}System.out.println("--------------element end---------------------");break;case Node.TEXT_NODE:printNodeInfo(node);break;default:break;}/* * 递归调用 */Node child = node.getFirstChild();while (child != null) {printNode(child);child = child.getNextSibling();}}public static void main(String[] args) {DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();try {DocumentBuilder db = dbf.newDocumentBuilder();Document doc = db.parse(new File("bin/students.xml"));DOMPrinter domPri = new DOMPrinter();domPri.printNode(doc);} catch (ParserConfigurationException e) {e.printStackTrace();} catch (SAXException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}
