我要评论引入 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
