Need help extracting optionbutton values from a word document

Question

I have a word document that contains text fields, form fields, and option buttons that I need to process automatically with C#. I can use the formfields collection to extract the text and form fields, but when it comes to the option buttons (radio buttons) I am struggling on where to look to access them. I've tried the contentcontrols collection, since the option buttons are activex controls, I assumed they would fall there but alas the collection is empty when I access it. I would prefer to use word automation controls to do so (Microsoft.Office.Interop.Word) but am open to any suggestions.

The document was created in Word 2007 using the developer tools. I can post an example document if necessary, but am unable to post the document that I'm trying to read given it's proprietary nature.

Any insight is much appreciated.

Thanks

Was able to identify a solution, possibly not ideal given OpenXML, but will work for what I need.

     Microsoft.Office.Interop.Word.Application a = new Microsoft.Office.Interop.Word.Application ();
     Document d = a.Documents.Open 
        ( "afile.docx", 
          Type.Missing, 
          Type.Missing, 
          Type.Missing, 
          Type.Missing, 
          Type.Missing, 
          Type.Missing, 
          Type.Missing, 
          Type.Missing, 
          Type.Missing, 
          Type.Missing, 
          Type.Missing, 
          Type.Missing, 
          Type.Missing, 
          Type.Missing, 
          Type.Missing );

     d.ActiveWindow.Selection.WholeStory ();
     d.Activate ();

     foreach ( InlineShape isp in d.InlineShapes)
     {
        Console.WriteLine 
           ( "{0}: {1}, {2}", 
             isp.OLEFormat.Object.Name, 
             isp.OLEFormat.Object.Caption, 
             isp.OLEFormat.Object.Value );
     }
