javaxml对象(java对xml有哪些解析技术)

导语：java程序中xml格式对象与xml字符串互转

(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 = &34;;        // 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(&34;);        System.out.println(&34; + eleHello.getText());        List<Element> elementList = rootElement.elements(); // 根下元素集合        String convertXml = documentDe.asXML();        System.out.println(&34; + 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(&34;));        Element rootEle = document.getRootElement();        Element helloEle = rootEle.element(&34;);        System.out.println(&34; + helloEle.getText());    }public static void main(String[] args) throws Exception {// 测试代码        new Helloworld().xmlFromFile();}}

测试xml文件：x1.xml
