Document -->XML报文传输与解析，简单实例

import java.io.StringReader;

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

public class TestA {

	public static String test(){
		Document document = DocumentHelper.createDocument();
		Element element = document.addElement("aaaa");
		Element ele1 = element.addElement("bbbb");
		Element ele2 = element.addElement("cccc");
		ele1.addText("1");
		ele2.addText("你好");
		return document.asXML();
	}

	public static void main(String[] args) {
		String test = test();
		System.out.println(test);
		StringReader stringReader = new StringReader(test);
		SAXReader reader = new SAXReader();
		Document doc = null;
		try {
			doc = reader.read(stringReader);
		} catch (DocumentException e) {
			e.printStackTrace();
		}
		Element element = doc.getRootElement();
		String resultCode = element.elementText("bbbb");
		String resultMsg = element.elementText("cccc");
		System.err.println("[aaaa]" + resultCode);
		System.err.println("[bbbb]" + resultMsg);
	}
}

结果：

<?xml version="1.0" encoding="UTF-8"?>
<aaaa><bbbb>1</bbbb><cccc>你好</cccc></aaaa>
[aaaa]1
[bbbb]你好
