Incorporate altchunks into docx document

[Chunk]

Hi,

Actually I’ve found semi-solution with the use of Interop. I was able to open, tidy and update TOC for that document with the following code:

var wordApplication = new Application();
var document = wordApplication.Documents.Open(FileName: filePath, OpenAndRepair: true);

document.TablesOfContents[1].Update();
document.SaveAs(filePath);

document.Close();
wordApplication.Quit();

Anyway if there’s some neat way to do it without the Interop I’d still be grateful.

Ok, so I managed to come up with a solution. In order to insert a document at a certain position I split the original document into two sources for the DocumentBuilder, then I created a source from the document to be inserted. In the end I built a new document with these 3 sources and it seems to be working just fine.

I am looking for the paragraph to split the original document by a placeholder, for example “@@insert@@”.

Bellow is the code if anyone needs it.

var paragraph = DestinationDocument.MainDocumentPart.Document.Descendants<OpenXmlParagraph>().FirstOrDefault(item => item.InnerText.Contains(placeHolder));

if (paragraph != null)
{
var idOfParagraph =
DestinationDocument.MainDocumentPart.Document.Descendants<OpenXmlParagraph>()
.ToList()
.IndexOf(paragraph);

//save and close current destination document
SaveChanges(destinationFilePath, false);

var sources = new List<Source>();

var originalDocument = new WmlDocument(destinationFilePath);

sources.Add(new Source(originalDocument, 0, idOfParagraph, true)); // add first part of initial document

var documentToBeInserted = new WmlDocument(docFilePath);
sources.Add(new Source(documentToBeInserted, true)); // add document to be inserted

sources.Add(new Source(originalDocument, idOfParagraph + 1, true)); // add rest of initial document

var newDestinationDocument = DocumentBuilder.BuildDocument(sources); // build new document
newDestinationDocument.SaveAs(destinationFilePath); // save

// re-open destination document
DestinationDocument = WordprocessingDocument.Open(Path.GetFullPath(destinationFilePath), true);
}
