(1) java程序中xml格式对象与xml字符串互转

import org.dom4j.Document;import org.dom4j.DocumentHelper;import org.dom4j.Element;public class Helloworld {    private void xmlDocument() throws Exception {        String xmlStrs = "<root><hello>helloContent1</hello></root>";        // 解析xml字符串获取Document对象        Document documentDe = DocumentHelper.parseText(xmlStrs);        Element rootElement = documentDe.getRootElement();        // 1 获取根节点下元素 2 其节点内容        Element eleHello = rootElement.element("hello");        System.out.println("节点内容：" + eleHello.getText());        List<Element> elementList = rootElement.elements(); // 根下元素集合        String convertXml = documentDe.asXML();        System.out.println("格式xml对象转换xml字符串：" + convertXml);    }	public static void main(String[] args) throws Exception {		// 测试代码        new Helloworld().xmlDocument();	}}

(2) java程序中从xml文件获取节点字符串

import org.dom4j.Document;import org.dom4j.Element;import org.dom4j.io.SAXReader;public class Helloworld {	private void xmlFromFile() throws Exception {        SAXReader saxReader = new SAXReader();        Document document = saxReader.read(new File("F:\\xbl\\x1.xml"));        Element rootEle = document.getRootElement();        Element helloEle = rootEle.element("hello");        System.out.println("这是从xml文件获取xml节点字符串：" + helloEle.getText());    }	public static void main(String[] args) throws Exception {		// 测试代码        new Helloworld().xmlFromFile();	}}

测试xml文件：x1.xml
