我正在使用带有标签的asp网络应用程序。当我单击该选项卡时，将读取xml文件。该xml文件中包含数据。该xml文件具有指向xslt文件的href，其中我编写了用于创建表的代码，用于在浏览器中以可呈现的方式在xml文件中显示xml数据。
用户可以更改xml文件中的数据，也可以在运行时删除一些数据。我在xslt文件中包含了一个刷新按钮。在运行时，如果用户对xml文件进行了更改，我希望单击刷新按钮以反映网页中表格中的更改。我只想刷新xml文件，相应的更改将反映在网页中。
我该怎么做？我已在上面上传了我的代码：

答案 0 :(得分：0)
您可以使用setTimeout函数在客户端设置计时器。 每次你可以阅读xml并检查修改日期 的文件。或者例如在XML changedDate中设置属性并检查它 每次。如果它从前一个更改，您可以刷新xml。
答案 1 :(得分：0)
正如我之前所说，您可以检查xml的修改数据或在XML中设置属性“ModifiedDate”。 当有人更新XML时，他必须更改更新attribure。
