Hi everyone,

I am trying to create a powerpoint document in Matlab using openXML SDK 2.5. It is going well so far, but an office presentation require a "slideidlist" to be append (which is just to add sibling node in the xml). I do not understand why the function does nothing, no eror, no result.

Any of you have experienced that behaviour with .NET function?

Thank you,

%Declare
NET.addAssembly('C:\Program Files (x86)\Open XML SDK\V2.5\lib\DocumentFormat.OpenXml.dll')
NET.addAssembly('System.Xml')
NET.addAssembly('System.IO')
NET.addAssembly('System.Collections')
%Open doc (with 0 slide, just a master)
type=DocumentFormat.OpenXml.Packaging.PresentationDocument;
docP=type.Open('c:\local\test4.pptx',true);
% Add SlideIdList to empty doc
docP.PresentationPart.Presentation.SlideIdList=...
        DocumentFormat.OpenXml.Presentation.SlideIdList;
slideId=DocumentFormat.OpenXml.Presentation.SlideId;
slideId.Id = DocumentFormat.OpenXml.UInt32Value('65487545654'); %any value
slideIdList=docP.PresentationPart.Presentation.SlideIdList;
%Try to append, but no error, not on the resulting XML either. Haschildren still 0
slideIdList.Append(slideId)
