DOM4J读取XML

   加入jar包 ：DOM4J.jsr

1、XML文件

<?xml version="1.0" encoding="UTF-8"?>
<school id="school1">
	<class id="one">
		<student id="001">
			<name>Array</name>
			<sex>男</sex>
		</student>
		<student id="002">
			<name>List</name>
			<iden>
				<sex>男</sex>
				<phone>1234567</phone>
			</iden>
		</student>
	</class>
	<class id="two">
		<student id="003">
			<name>Array</name>
			<sex>男</sex>
		</student>
		<student id="004">
			<name>List</name>
			<sex>女</sex>
		</student>
	</class>
</school>

2、读取数据

public static void main(String[] args) throws ParserConfigurationException, SAXException, DocumentException {
		File f = new File("E:\\WorkSpace\\EclipseWork\\JAVA_DEMO\\src\\net\\ylj\\xml\\test.xml");
		SAXReader reader = new SAXReader();
		Document doc = reader.read(f);
		//获取根节点
		Element element = doc.getRootElement();
		print(element);
			
	}
	private static void print(Element element){
		List<Element> list = element.elements();
		for(Element e : list){
			if(e.isTextOnly()){
				System.out.println(e.getText());
			}else{
				print(e);
			}
		}
	}
