通过Java读取xml文件内容过程解析

    //1.创建SAXReader对象用于读取xml文件
    SAXReader reader = new SAXReader();
    //2.读取xml文件，获得Document对象
    Document doc = reader.read(new File("src/book.xml"));
    //3.获取根元素
    Element root = doc.getRootElement();
    //4.获取根元素下的所有子元素（通过迭代器）
    Iterator<Element> it = root.elementIterator();
    while(it.hasNext()){
       
      Element e = it.next();
      //获取id属性(attribute是属性的意思)
      Attribute id = e.attribute("id");
      System.out.println(id.getName()+" = "+id.getStringValue());
      Element author = e.element("author");
      Element money = e.element("price");
      Element time = e.element("time");
      System.out.println(author.getName()+" = "+author.getStringValue());
      System.out.println(money.getName()+" = "+money.getData());
      System.out.println(time.getName()+" = "+time.getText());
      System.out.println("---------------------------------------------------------------");
    }
