Troubles with documents including an altchunk part


I have a document which includes an altchunk. If I open this document with Aspose.Word and modify somthing in document and save it all altchunk parts are removed.

Is this a known problem of Aspose.Word?

Hi Christian,

Thanks for your inquiry. Could you please attach your input Word document here along with code for testing? I will investigate the issue on my side and provide you more information.

Currently AltChunk is supported during conversions but there is no public API to work with this feature.

Attached is my document and the code is following:

// Open document from stream
 Aspose.Words.Document aspDoc = new Aspose.Words.Document(mem);
 Aspose.Words.DocumentBuilder docBuilder = new Aspose.Words.DocumentBuilder(aspDoc);
Aspose.Words.NodeCollection sdtcoll = aspDoc.GetChildNodes(Aspose.Words.NodeType.StructuredDocumentTag, true);
 Aspose.Words.SaveFormat docSaveFormat = Aspose.Words.SaveFormat.Docx;
 //Save it back into another stream
docSaveFormat = Aspose.Words.SaveFormat.Docx;
aspDoc.Save(dstStream, docSaveFormat);
