dom4j将元素转换为字符串

使用dom4j将元素转换为字符串可以使用XMLWriter类，示例如下：

import java.io.StringWriter;
import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.XMLWriter;

public class Dom4jElementToString {
    public static void main(String[] args) {
        Document document = DocumentHelper.createDocument();
        Element root = document.addElement("root");
        Element child = root.addElement("child");
        child.addAttribute("attribute", "value");
        child.addText("text");

        StringWriter writer = new StringWriter();
        OutputFormat format = OutputFormat.createPrettyPrint();
        XMLWriter xmlWriter = new XMLWriter(writer, format);
        try {
            xmlWriter.write(document.getRootElement());
            xmlWriter.flush();
            System.out.println(writer.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

输出结果：

<root>
  <child attribute="value">text</child>
</root>
