GetXDocument fails for VMLPart.

[princraiParticipant]

Hi Eric,

I was trying to run PresentationBuilder for one of the PPT document and it was failing at vmlPart.GetXDocument(). I am able to open the PPT document successfully but when running through the PresentationBuilder it throws an exception for vmlPart.GetXDocument() saying (‘if’ is an unexpected token. The expected token is ‘CDATA[‘. Line 55, position 6.). Pasted the vmlDrawings.vml below:
<![if gte mso 9]> is the line at which it throws the exception. I am not sure if I am able to open the PPT document why are we not able to load the xml in GetXDocument().

Hi,

VML is strange – it looks like XML, but it is not.

There is, I recall, a way to ‘hack’ the VML so that it can be read by an XML parser, but I don’t recall the details.

Right now, I am fully engaged in completing a module that enables comparing two DOCX files and producing another file that contains tracked revisions, and contractually need to finish this ASAP, so can’t spend any time researching this. However, I do recall doing this at one point.

Question – why are you using a presentation that contains VML? It is deprecated. If you load the presentation in PowerPoint, and then specify the right option, then I believe that you can save the presentation in such a way that it replaces VML with DrawingML.

Hi Eric,

Thanks for the response. Basically as I mentioned in my earlier posts, we are using PresentationBuilder to extract objects out of it. We load the document and extract these object. I just got an document for which I am able to open in PowerPoint but when I ran through the PresentationBuilder it fails for that vml object. It will be great if you can let me know how I can either convert the vml into drawingxml(programmatically) or by any how hack the vml thing.

Thanks,
Prince
