Refreshing the xml file through button
I am using an asp web application that has a tab. When I click on that tab, an xml file is read. That xml file has data in it. That xml file has a href pointing to an xslt file where I have written code for creating a table for displaying the xml data in the xml file in a presentable manner in the browser.
The user may change the data in the xml file or he may remove some data too, during runtime. I have included a refresh button in the xslt file. During runtime, if the user makes changes to the xml file, I wish to click on the refresh button to reflect the changes in the table in web page. I just want the xml file to be refreshed and the corresponding changes to be reflected in the web page.
How do I do this? I have uploaded my code below :

You can set at the client side timer using setTimeout function. Eeach time you can read the xml and check modified date of the file. Or for example to set attribute in XML changedDate and to check it each time.If it's changed from previous one you can refresh the xml .
So as I stated previously you can check modified data of xml or to set attribute "ModifiedDate" in XML . When someone updates XML , he must change update the attribure.
