I need to restrict the uploaded file to only accept an xml file
in an html form tried writing
<INPUT TYPE="file" NAME="myFile1" accept="text/xml"> but accepts all types of files

You need to check the file type through javascript.

/*To check file extensions */

function checkFileExtension( parafilevalue ){
  var file = parafilevalue.split('.');
  var validType = false;

  if( file.length < 2 ){
   return false;
  }

  var fileext = file[1].toLowerCase();
  if( fileext == 'xml' ) {
   validType = true;
  }

return validType;

}
