Merging documents using OpenXml and section breaks causes empty paragraphs

I am stitching a couple of documents together with a requirement that each document should retain its header and footer information in the final document. Using AltChunk instead of raw OpenXml or DocumentBuilder saves a lot of effort with regards to styles, formatting, references, parts, etc.

Unfortunately, after a couple of days I can't seem to get a 100% working version due to a small and frustrating issue and I need some insight.

My code is loosly based on this article

I modify each sub document, prior to appending it (as an AltChunk) to a working document, by moving the last section properties into the last paragraph (in order to retain header and footer references), but Word seems to be adding a blank paragraph to each of these documents as it renders them in the final document. I end up with:

document 1 with correct header and footer section properties/break blank paragraph document 2 with correct header and footer section properties/break blank paragraph etc.

I cant remove the blank paragraphs afterwards, as I ideally don't want to use WAS to render the document first.

It seems as if you cannot have a next-page section break without a following paragraph?

I have the similar empty paragraph issue while importing HTML files.

My solution is,

After inserting HTML AltChunk, I add a GUID place holder. After processing the file, I will open the file again, locate the GUID and check if there is a empty paragraph before it, if so remove the empty paragraph and GUID. it seems work perfectly in my solution.

Hope it helps.

I'm using Document Builder and works perfectly for me!

 var sources = new List<OpenXmlPowerTools.Source>();

 sources.Add(new OpenXmlPowerTools.Source(new WmlDocument(@tempReportPart1)));
 sources.Add(new OpenXmlPowerTools.Source(new WmlDocument(@tempReportPart2)));        

 var outputPath = @"C:\Users\xpto\Documents\TestFolder\myNewDocument.docx";

 DocumentBuilder.BuildDocument(sources, outputPath);

After further investigation, it seems that will not be away around my usage scenario. I would need to place the last section properties in the body element, but due to my way of processing with nested AltChunk, it would not work.

I have changed my approach completely and went back to a more detailed append procedure using OpenXml Power Tools and some LINQ to Xml.
