this is my "path/to/file.qml"
Qt Code: 
  1. Rectangle{
  2. id::root
  3. property string mystring:"Hello"
  4.  
  5.             Button{
  6.                 id: btnTest
  7.                 width:140
  8.                 height: 30
  9.                 text: "btnTest"
  10.                 onClicked: {
  11.                     console.log(root.mystring)
  12.  
  13.             }
  14.  
  15. MyPlugin{
  16.  id:plugin1
  17. Component.onCompleted: {
  18.  
  19.         }
  20. }
  21.  
  22. }

Yes you are right. The qml.exe is loading 'path/to/file.qml' and then my plugin is also handling the 'path/to/file.qml' file.
My goal is to modify loaded qml file through the plugins in it...
