第一种解析方法
----------------------------------------------------------------DOM解析方式----------------------------------------------------
public class DOMxml { List<Tv> list = new ArrayList<Tv>(); public static void main(String[] args) throws Exception { // 创建一个DocumentBuilderFactory的对象 DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); // 创建一个DocumentBuilder对象 try { // 创建一个DocumentBuilder对象 DocumentBuilder db = dbf.newDocumentBuilder(); // 创建DocumentBuilder对象的parse方法加载xml文件 Document document = db.parse("凤凰卫视.xml"); // 获取所有Program节点的集合 NodeList Programlist = document.getElementsByTagName("Program"); // System.out.println(Programlist.getLength()); // 遍历 Tv tv = new Tv(); for (int i = 0; i < Programlist.getLength(); i++) { Node node = Programlist.item(i); NodeList nodes = node.getChildNodes(); for (int j = 0; j < nodes.getLength(); j++) { // 区分textnode以及element类型的node if (nodes.item(j).getNodeType() == Node.ELEMENT_NODE) { // Element child=(Element)nodes.item(j); // System.out.println(child.getTextContent()); // 获取element的节点名 Node node2 = nodes.item(j); // 获取节点名 String nodeName = node2.getNodeName(); System.out.print(nodeName + ":"); // 获取节点值 // String // nodeValue=node2.getFirstChild().getNodeValue(); String nodeValue = node2.getTextContent(); // tv.setPlayTime(nodeValue.substring(1)); System.out.println(nodeValue); } } } } catch (Exception e) { e.printStackTrace(); } /*DOMxml doMxml=new DOMxml(); doMxml.load();*/ } /*public void load() throws DocumentException{ Tv tv = new Tv(); InputStream is = this.getClass().getResourceAsStream("/"+"凤凰卫视.xml"); Document doc = new SAXReader().read(is); Element rootElement = doc.getRootElement(); Element mentElement=(Element)rootElement.elementIterator("ProgramList").next(); for (Iterator<Element> ment=mentElement.elementIterator("Program"); ment.hasNext();) { Element next = ment.next(); System.out.println(next); String playtime=next.attributeValue("playTime"); String name=next.attributeValue("name"); String path=next.attributeValue("path"); System.out.println(name); System.out.println(path); System.out.println(playtime); tv.setPlayTime(playtime); tv.setName(name); tv.setPath(path); }*/ }-------------------------------------------------------第二种SAX解析------------------------------------------------------------------
SAXParserHandler类
public class SAXParserHandler extends DefaultHandler { int count =0; String value=null; Tv tv=null; private ArrayList<Tv>list=new ArrayList<Tv>(); /** * 用来解析xml元素 */ @Override public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException { // 调用DefaultHandler的startElement方法 super.startElement(uri, localName, qName, attributes); if (qName.equals("Program")) { // 获取属性值 count++; System.out.println("-------------开始遍历"+count+"的内容--------------"); int length = attributes.getLength(); // 获取对应节点的属性值 String value = attributes.getValue(""); }else if(!qName.equals("Program")&&!qName.equals("ProgramList")&&!qName.equals("typeB")){ System.out.print("节点名为："+qName); } } /** * 用来标识解析开始 */ @Override public void startDocument() throws SAXException { super.startDocument(); System.out.println("--------------SAX解析开始---------------"); } /** * 解析结束 */ @Override public void endDocument() throws SAXException { // TODO Auto-generated method stub super.endDocument(); System.out.println("----------SAX解析结束---------------"); } /** * 调用DefaultHandler的endElement方法 */ @Override public void endElement(String uri, String localName, String qName) throws SAXException { // TODO Auto-generated method stub super.endElement(uri, localName, qName); if (qName.equals("Program")) { //list.add(tv); System.out.println("-------结束遍历"+count+"的内容---------"); }/*else if (qName.equals("playTime")) { tv.setPlayTime(value); }else if (qName.equals("name")) { tv.setName(value); }else if (qName.equals("path")) { tv.setPath(value); }*/ } /** * 获取节点值 */ @Override public void characters(char[] ch, int start, int length) throws SAXException { // TODO Auto-generated method stub super.characters(ch, start, length); value = new String(ch, start, length); if (!value.trim().equals("")) { System.out.println("\t节点值为："+value); } } public ArrayList<Tv> getList() { return list; } } -------------------main方法-------------------------------- public static void main(String[] args) { // 获取一个SAXParserFactory实例 SAXParserFactory spf = SAXParserFactory.newInstance(); //通过factory获取SAXParser实例 try { SAXParser sp=spf.newSAXParser(); //创建SAXParserHandler对象 SAXParserHandler sph=new SAXParserHandler(); sp.parse("凤凰卫视.xml",sph); //System.out.println("共有"+sph.getList().size()); } catch (Exception e) { e.printStackTrace(); } }
