The goal is to develop an AngularJS-based interface that allows users to upload XML files, specifically restricting the selection to XML formats only. This involves creating a button that utilizes the ng-click directive to trigger the file upload process. Upon uploading, the application should validate that the uploaded file is a proper XML document, before using it to replace predefined XML constants in the program. The constants include form1, form2, and form3, which are imported from another file. The uploaded XML should seamlessly replace the imported forms within the application's scope objects.
I am trying to implement an AngularJS solution that allows users to upload XML files, overriding existing constants in my code based on user input.
