Merging 2 word 2007(open xml) documents

I had to merge 2 word documents once.

They were both in word 2007(open xml) format.

I searched online everywhere for a way to merge them.

All the links were about using the altChunk element. I have a problem with that. The entire document gets put in there and that is a lot of unneeded data(like header and footer etc.).

So I did it another way:

1. cloned the second document's body

2. cloned all it's children and added them to the first document's main part

	static void MergeDocs(string doc1Path,string doc2Path)
	{
	using (var doc2FileStream = File.Open(doc2Path, FileMode.Open))
	{
	using (WordprocessingDocument doc2 = WordprocessingDocument.Open(doc2FileStream, true))
	{
	var doc2Body = (Body)doc2.MainDocumentPart.Document.Body.CloneNode(true);
	using (var doc1FileStream = File.Open(doc1Path, FileMode.Open))
	{
	using (WordprocessingDocument doc1 = WordprocessingDocument.Open(doc1FileStream, true))
	{
	var mainPart = doc1.MainDocumentPart;
	foreach (var elem in doc2Body.ChildElements)
	{
	if (!(elem is SectionProperties))
	mainPart.Document
	.Body
	.InsertAfter(elem.CloneNode(true), mainPart.Document.Body.Elements<paragraph>().Last());
	}
	mainPart.Document.Save();
	}
	}
	}
	}
	}
