【解决方案1】：

您可以使用JSOUP 以String 获取您的数据

1.) 使用Jsoup.parse(your_string)将字符串作为文档获取

2.) 使用document.getAllElements() 作为元素获取所有节点

3.) 遍历元素并使用ownText()函数获取数据

    Document document=Jsoup.parse(your_response);
    Elements elements = document.getAllElements();
    for (Element element : elements) {
        String data =element.ownText();
        // some strings are empty so avoid them
        if (!data.isEmpty()) {
            System.out.println(data);               
        }
    }

输出
