using the following code snippet I open a document template (DOTX) and then append another document. Both have bookmarks.
Dim m_word As WordprocessingDocument = = WordprocessingDocument.Open("FrontPage.dotx", True)
Dim altChunkId As String = "ChunkId1"
Dim mainPart As MainDocumentPart = m_word.MainDocumentPart
Dim chunk As AlternativeFormatImportPart = mainPart.AddAlternativeFormatImportPart(
DocumentFormat.OpenXml.Packaging.AlternativeFormatImportPartType.WordprocessingML, altChunkId)
Using fileStream As IO.FileStream = IO.File.Open("Appendix.dotx", IO.FileMode.Open)
chunk.FeedData(fileStream)
End Using
Dim altChunk As AltChunk = New DocumentFormat.OpenXml.Wordprocessing.AltChunk()
altChunk.Id = altChunkId
mainPart.Document.Body.InsertAfter(altChunk, mainPart.Document.Body.Elements(Of DocumentFormat.OpenXml.Wordprocessing.Paragraph).Last())
mainPart.Document.Save()
Now if I try to loop trough all bookmarks like this:
Dim docbody As Body = doc.GetFirstChild(Of Body)()
For Each bookmarkStart As BookmarkStart In docbody.Descendants(Of BookmarkStart)()
' Do something with the bookmarks
Next
I only get the bookmarks of the original frontpage.dotx, none of the bookmarks of the appendix.dotx is found. If I save the document to a file, all the bookmarks are there when I open it using Word. I can also reopen the saved file i C# and then all bookmarks can be found using the above For Each loop. The question is, how can I get all the bookmarks after appending without saving and reloading the document?
When you use AltChunk to embed a document the entire file is embedded into the document - it's NOT integrated. That only happens when the combined document is opened by Word. If you need to work through all the bookmarks you need to either
