JDOM解析

JDOM

解析實力:

public class JDOMParser {
    private static ArrayList<Book> booksList = new ArrayList<Book>();

    public static void main(String[] args) {
        Book bookEn=null;
        //進行對books.xml文件的JDOM解析
        //1.創建一個SAXBulider對象
            SAXBuilder saxBuilder = new SAXBuilder();
        InputStream in ;
        try {
        //2.創建一個輸入流，將xml文件加載到輸入流中
        in = new FileInputStream("books.xml");
        //3.通過saxBuilder對象的build方法，將輸入流加載到saxBuilder對象中
        Document document = saxBuilder.build(in);
        //4.通過document對象獲取xml文件的根節點
        Element  rootElement = document.getRootElement();
        //5.獲取根節點下的子節點的集合
        List<Element> bookList = rootElement.getChildren();
        for (Element book : bookList) {
            System.out.println("開始解析第"+(bookList.indexOf(book)+1)+ "本書");
            //解析book屬性
            List<Attribute> attrList = book.getAttributes();
            for (Attribute attr : attrList) {
            bookEn = new Book();
            //獲取屬性名，屬性值
            String name = attr.getName();
            String value = attr.getValue();
            System.out.println("屬性名:"+name +"--屬性值："+value);
            if(attr.getName().equals("id")){
                bookEn.setId(value);
                }
            }
            List<Element> childList = book.getChildren();
            for (Element child : childList) {
            System.out.println("節點名："+child.getName()+"--節點值："+child.getValue());
            if(child.getName().equals("name")){
                bookEn.setName(child.getValue());

            }else if(child.getName().equals("price")){
                bookEn.setPrice(child.getValue());
            }else if(child.getName().equals("language")){
                bookEn.setLanguage(child.getValue());
            }
        }
            System.out.println(bookEn);
            System.out.println("結束解析第"+(bookList.indexOf(book)+1+ "本書");
            booksList.add(bookEn);
            bookEn = null;
            System.out.println(booksList.size());
            }
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (JDOMException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
