You have to upload it first and then read it to check its validity.

Try this

Just read this and add some more code in it

C#

XElement element;

TRY
 {
    element=XElement.Load(filename);
    -- Add code to updload file here
    --Because if you reach here then it meant your file successfully 
 }
CATCH (exception ex)
 {
    -- Do not upload file and write code to handle invalid XML file
 }
