[pde-dev] Selection Text doesn't work !!!

["Eclipse Questions" <eclipse.questions@xxxxxxxxx>]

Hi,

 

I need to select text and insert text in all the editors.

While I can do the same when I open a file with text editor. The same doesn't work when i open it with XML Editor.

 

I have a ActionDelegate subclass that has the following code in the run method:

 

 

  // get the opened document  
  IEditorPart part = PlatformUI.getWorkbench().getActiveWorkbenchWindow()
    .getActivePage().getActiveEditor();
  IEditorSite site = part.getEditorSite ();
  TextFileDocumentProvider docProvider = new TextFileDocumentProvider();
  try {
    docProvider.connect(part.getEditorInput());
  } catch (CoreException e) {
   e.printStackTrace();
  }
  IDocument doc = docProvider.getDocument(part.getEditorInput());

 

// get the cursor position/selected area in the editor

 ISelection selection = site.getSelectionProvider().getSelection();
  
   try {
    // get the selected text
   String selectedText = ((ITextSelection)selection).getText();

    System.out.println(" Selected text : " + selectedText);

    // insert a text
   start = ((ITextSelection)selection).getOffset();
   doc.replace(start, 0, "init section #1 starts here .... ends here");
   } catch (BadLocationException exp) {

      e.printStackTrace();
   }

 

 

selectedText is null when its XML Editor. Even though the XML editor displays the xml file as set of characters like a text editor, why i cannot acheive the functionality ?

 

Please help me ASAP.

 

Thanks
