I realize I'm 7 years late to the game here. Still, for future people searching on how to convert from HTML to Word Doc, this blog posting on a Microsoft MSDN site gives most of the ingredients necessary to do this using OpenXML. I found the post itself to be confusing, but the source code that he included clarified it all for me.
The only piece that was missing was how to build a Docx file from scratch, instead of how to merge into an existing one as his example shows. I found that tidbit from here.
Unfortunately the project I used this in is written in vb.net. So I'm going to share the vb.net code first, then an automated c# conversion of it, that may or may not be accurate.
vb.net code:
Imports DocumentFormat.OpenXml
Imports DocumentFormat.OpenXml.Packaging
Imports DocumentFormat.OpenXml.Wordprocessing
Imports System.IO
Dim ms As IO.MemoryStream
Dim mainPart As MainDocumentPart
Dim b As Body
Dim d As Document
Dim chunk As AlternativeFormatImportPart
Dim altChunk As AltChunk
Const altChunkID As String = "AltChunkId1"
ms = New MemoryStream()
Using myDoc = WordprocessingDocument.Create(ms,WordprocessingDocumentType.Document)
mainPart = myDoc.MainDocumentPart
If mainPart Is Nothing Then
mainPart = myDoc.AddMainDocumentPart()
b = New Body()
d = New Document(b)
d.Save(mainPart)
End If
chunk = mainPart.AddAlternativeFormatImportPart(AlternativeFormatImportPartType.Xhtml, altChunkID)
Using chunkStream As Stream = chunk.GetStream(FileMode.Create, FileAccess.Write)
Using stringStream As StreamWriter = New StreamWriter(chunkStream)
stringStream.Write("YOUR HTML HERE")
End Using
End Using
altChunk = New AltChunk()
altChunk.Id = altChunkID
mainPart.Document.Body.InsertAt(Of AltChunk)(altChunk, 0)
mainPart.Document.Save()
End Using
c# code:
using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Wordprocessing;
using System.IO;
IO.MemoryStream ms;
MainDocumentPart mainPart;
Body b;
Document d;
AlternativeFormatImportPart chunk;
AltChunk altChunk;
string altChunkID = "AltChunkId1";
ms = new MemoryStream();
Using (myDoc = WordprocessingDocument.Create(ms, WordprocessingDocumentType.Document))
{
mainPart = myDoc.MainDocumentPart;
if (mainPart == null)
{
mainPart = myDoc.AddMainDocumentPart();
b = new Body();
d = new Document(b);
d.Save(mainPart);
}
chunk = mainPart.AddAlternativeFormatImportPart(AlternativeFormatImportPartType.Xhtml, altChunkID);
Using (Stream chunkStream = chunk.GetStream(FileMode.Create, FileAccess.Write)
{
Using (StreamWriter stringStream = new StreamWriter(chunkStream))
{
stringStream.Write("YOUR HTML HERE");
}
}
altChunk = new AltChunk();
altChunk.Id = altChunkID;
mainPart.Document.Body.InsertAt(Of, AltChunk)[altChunk, 0];
mainPart.Document.Save();
}
Note that I'm using the ms memory stream in another routine, which is where it's disposed of after use.
I hope this helps someone else!
