title: Fill HTML5 Input Fields with Uploaded XML File
body: <p>I built an HTML5/JS web application that performs fairly complicated mathematical calculations based on user-provided data.  The application works by having several different input fields where users manually type in the information, then submit it for processing.  Much of the information that the users input will not change very often (but often enough where hard-coding it would not be economical), and I was interested in seeing if there was a way to allow users to upload XML files with all of the required data custom tailored to each user.  The fields would be filled automatically.  The user would change their particular XML file as needed to reflect new values prior to getting new computations.  Just as an aside, anything server-side is not an option.</p>
  
  <p>Is it possible using HTML5/JS to upload an XML file, read the file contents, and fill input fields automatically?</p>
