如何在java脚本中从xml响应体中获取值

public class XMLParser {

        String xmlResponse = "<response><data>这是需要获取的值</data></response>";

        try {
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = factory.newDocumentBuilder();
            Document document = builder.parse(new InputSource(new StringReader(xmlResponse)));

            // 获取根元素
            Element root = document.getDocumentElement();

            // 通过标签名获取节点列表
            NodeList nodeList = root.getElementsByTagName("data");

            // 遍历节点列表并获取值
            for (int i = 0; i < nodeList.getLength(); i++) {
                Node node = nodeList.item(i);
                if (node.getNodeType() == Node.ELEMENT_NODE) {
                    Element element = (Element) node;
                    String value = element.getTextContent();
                    System.out.println("获取到的值: " + value);
                }
            }
        } catch (ParserConfigurationException | SAXException | IOException e) {
            e.printStackTrace();
        }
    }
}
