代码如下：

SAXBuilder builder = new SAXBuilder();
        Document doc = builder.build(new File("C:\\a.xml"));

        Element root = doc.getRootElement();
        String rootName = root.getName(); //"person"
        List dataList = root.getChildren();

        Iterator i = dataList.iterator();
        while (i.hasNext()) {
         Element e = (Element) i.next();
         String eKey = e.getName(); //"name","age","address"
         String eValue = e.getText(); //"wang","22","beijin"
         System.out.println("eKey==="+eKey+"  ;eValue==="+eValue);
        }
