在Java DOM中将节点的内部XML作为String获取

// 导入相关的类
import javax.xml.transform.*;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;

// 获取要处理的节点对象
Node node = ...;

// 创建转换器工厂和转换器对象
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();

// 将节点转换为字符串
StringWriter writer = new StringWriter();
transformer.transform(new DOMSource(node), new StreamResult(writer));
String xmlString = writer.toString();
