JAVA解析XML字符串简单方法代码案例

引入 dom4j 包

				?

									<dependency>

									　　<groupId>dom4j</groupId>

									　　<artifactId>dom4j</artifactId>

									　　<version>1.6.1</version>

									</dependency>

比如阿里云视频转码服务的回调通知解析，代码如下：

				?

									import org.dom4j.Document;

									import org.dom4j.DocumentException;

									import org.dom4j.DocumentHelper;

									import org.dom4j.Element;

									import java.util.Iterator;

									public class DOMParser {

									  public static void main(String[] args) {

									    String strXML = "<?xml version=\"1.0\" encoding=\"UTF-8\"?> <Notification xmlns=\"http://mns.aliyuncs.com/doc/v1/\"> <TopicOwner>1692545896541241</TopicOwner> <TopicName>MyTopic</TopicName> <Subscriber>1692545896541241</Subscriber> <SubscriptionName>bing-test3</SubscriptionName> <MessageId>C39FB8C345BBFBA8-1-1687F6FAADD-200000015</MessageId> <MessageMD5>CAA1E9F5E9F854ACD8297B100BF8CCF9</MessageMD5> <Message>{\"jobId\":\"2384a4d89b1d4f1e869559e2ff8c9fad\",\"requestId\":\"639D1D03-1557-4AD7-9AD7-691F02834516\",\"Type\":\"Transcode\",\"state\":\"Success\",\"type\":\"Transcode\",\"State\":\"Success\",\"JobId\":\"2384a4d89b1d4f1e869559e2ff8c9fad\",\"RequestId\":\"639D1D03-1557-4AD7-9AD7-691F02834516\"}</Message> <PublishTime>1548326251229</PublishTime> </Notification>";

									    Document doc = null;

									    try {

									      doc = DocumentHelper.parseText(strXML);

									    } catch (DocumentException e) {

									      e.printStackTrace();

									    }

									    Element root = doc.getRootElement();// 指向根节点

									    Iterator it = root.elementIterator();

									    while (it.hasNext()) {

									      Element element = (Element) it.next();// 一个Item节点

									      System.out.println(element.getName() + " : " + element.getTextTrim());

									    }

									  }

									}

输出结果
