获取xml字符串中标签属性(单标签多属性)

开发的时候文件上传平台给我返回了一个xml格式的字符串，有文件ID和文件名称需要我返回给前端。
记录一下开发过程中xml字符串转实体类对象
实体类对象

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Pages {
    private String pageId;
    private String fileName;
    private String nodeId;
    private String nodeName;
    private String responseCode;
    private String responseMsg;
}

代码实现

public class test {
    public static void main(String[] args) {
        readStringXml();
    }
    @SuppressWarnings("unchecked")
    public static void readStringXml() {
        String xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
                "<root>\n" +
                "    <PAGES>\n" +
                "        <PAGE PAGEID=\"faklf21312op1234o1k132k3nk1\" FILE_NAME=\"test.xlsx\" NODE_ID=\"xxx_01\" NODE_NAME=\"xxxxxxxx\"/>\n" +
                "    </PAGES>\n" +
                "    <RESPONSE_CODE>1</RESPONSE_CODE>\n" +
                "    <RESPONSE_MSG>上传成功</RESPONSE_MSG>\n" +
                "</root>";
        try {
            Document doc = DocumentHelper.parseText(xml);
            // 将字符串转为XML
            Element rootElt = doc.getRootElement();
            // 获取根节点
            // 获取根节点的名称
            Pages pages = new Pages();
            Element page = rootElt.element("PAGES").element("PAGE");
            pages.setPageId(page.attributeValue("PAGEID"));
            pages.setFileName(page.attributeValue("FILE_NAME"));
            pages.setNodeId(page.attributeValue("NODE_ID"));
            pages.setNodeName(page.attributeValue("NODE_NAME"));
            pages.setResponseCode(String.valueOf(rootElt.element("RESPONSE_CODE").getStringValue()));
            pages.setResponseMsg(String.valueOf(rootElt.element("RESPONSE_MSG").getStringValue()));
            System.err.println(pages);
        } catch (DocumentException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
