如何在不知道xml结构时用jdom解析

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);
}
