dom4j写xml_dom4j 写出xml 空

  从官网上找来的，很简单

import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
 
public class Foo {
 
    public Document createDocument() {
        Document document = DocumentHelper.createDocument();
        Element root = document.addElement("root");
 
        Element author1 = root.addElement("author")
            .addAttribute("name", "James")
            .addAttribute("location", "UK")
            .addText("James Strachan");
 
        Element author2 = root.addElement("author")
            .addAttribute("name", "Bob")
            .addAttribute("location", "US")
            .addText("Bob McWhirter");
 
        return document;
    }
}
