我有一个xml文件，其中包含已在公司注册的员工详细信息。我使用本地服务器填充xml。我有一个登录页面，并有一个注册页面。我已成功将我的xml数据填充到数据网格中，无法通过文本输入字段更新或添加新员工。请帮助我完成在硬盘中更新我的xml文件所需的过程。

我看了你的代码＆amp;但是，我无法找到能够/可以写入XML文件的任何内容，例如写，重写 - 更新或添加???我看到的是简单的读出XML文件！关于aktell
答案 1 :(得分：0)
好的，我已将我的应用程序复制了几年，我已经使用了几年，而且它在我的服务器上运行，因此它已经得到了很好的证明，并且完美无缺！但当然这完全取决于我自己的要求，这些只是读写基础知识。希望能帮助您对自己的应用程序进行排序！ rgards aktell
我使用了TextInput组件!!!
