compare Shape object serialized out as xml with PP Shape object

Question

I have object Microsoft.Office.Interop.PowerPoint.Shape and I need to know if it is related (the same as) to object DocumentFormat.OpenXml.Presentation.Shape.

Maybe I can compare ID's? But to me looks like OpenXml.Presentation.Shape has a different id than PowerPoint.Shape.

Answer 1

I printed name and ID for two random shapes:

Oval 3
 4 
=========
Cross 4
 5 
=========

slide1.xml contained this:

      <p:sp>
          <p:nvSpPr>
              <p:cNvPr id="4" name="Ovaal 3"/>
              <p:cNvSpPr/>
              <p:nvPr/>
          </p:nvSpPr>
          ...
      </p:sp>

and

      <p:sp>
          <p:nvSpPr>
              <p:cNvPr id="5" name="Kruis 4"/>
              <p:cNvSpPr/>
              <p:nvPr/>
          </p:nvSpPr>
          ...
      </p:sp>

The only difference seems to be that the name is translated between Dutch and English, but the ID remains the same.
