//1.创建一个SAXBuilder的对象
SAXBuilder saxBuilder = new SAXBuilder();
//创建一个输入流，将XML文件加载到输入流
InputStream in;

//2、创建一个输入流，将xml文件加载到输入流中
in = new FileInputStream("src/res/books.xml");

//3、通过saxBuilder的Builder方法，将输入流加载到saxBuilder中
Document document = saxBuilder.build(in);

//通过document对象获取xml文件的根节点
Element rootElement = document.getRootElement();

//通过rootElement对象获取xml的子节点
List<Element> bookList= rootElement.getChildren();
//继续进行解析

for(Element book : bookList){
System.out.println("======开始解析第" + (bookList.indexOf(book) + 1) + "本书======");
//解析book属性结合
List<Attribute> attrList = book.getAttributes();
for(Attribute attr : attrList){
//遍历attrList属性名
String attrName = attr.getName();

//遍历attrList属性值
String attrValue = attr.getValue();

System.out.println("属性名: " + attrName + "----属性值  :" + attrValue);

//对book节点的节点名和值
