1 List booklist=new ArrayList();
2 String id="";
3 String title="";
4 String price="";
5 //获得实例工厂
6 DocumentBuilderFactory factory=DocumentBuilderFactory.newInstance();
7 //获得解析
8 DocumentBuilder builder=factory.newDocumentBuilder();
9 //获得document
10
11 Document document=builder.parse("books.xml");//根目录下失误books.xml
12
13
14 //获取所有book结点
15 NodeList element=document.getElementsByTagName("book");
16 //遍历book结点
17 for (int i = 0; i < element.getLength(); i++) {
18 //获取每一个book结点
19 Node node=element.item(i);
20 //结点转换为元素
21 Element bookElement=(Element)node;
22 id=bookElement.getAttribute("id");
23 //获取所有孩子结点
24 NodeList childNodeList=bookElement.getChildNodes();
25 //遍历结点
26 for (int c = 0; c < childNodeList.getLength(); c++) {
27 Node cNode=childNodeList.item(c);
28 //获取结点名字
29
30 String cName=cNode.getNodeName();
