How to convert open xml string to word document c#

Question

I am reading one element from code and I am getting Open XML string as a result.

  byte[] binary = Convert.FromBase64String(template.Attributes["body"].ToString());
  string bodyContent = UnicodeEncoding.UTF8.GetString(binary);

Now, I want to convert this string in memorystream so that it can be read by WordProcessingDocument as below.

  using (MemoryStream stream = new MemoryStream())
  {
      stream.Write(binary, 0, (int)binary.Length);
        using (WordprocessingDocument wordDoc = wordprocessingDocument.Open(stream, true))
          {
                File.WriteAllBytes("C:\\data\\newFileName.docx", stream.ToArray());
           }      
  }

When I try above code, it could not open stream and raises error of corrupted data.

XML string looks like :

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

Any idea on this?

Edits : As Per Gisha's suggestion, I have tried below code snippet and passed my xml string to content. Still it generates corrupted file.

// How to: Create a new package as a Word document.
  public static void CreateNewWordDocument(string document)
  {
   using (WordprocessingDocument wordDoc =  WordprocessingDocument.Create(document, WordprocessingDocumentType.Document))
   {
    // Set the content of the document so that Word can open it.
    MainDocumentPart mainPart = wordDoc.AddMainDocumentPart();

     SetMainDocumentContent(mainPart);
    }
   }

    // Set content of MainDocumentPart.
    public static void SetMainDocumentContent(MainDocumentPart part)
    {
    const string docXml =
        @"<?xml version=""1.0"" encoding=""UTF-8"" standalone=""yes""?> 
        <w:document xmlns:w=""http://schemas.openxmlformats.org /wordprocessingml/2006/main"">
        <w:body><w:p><w:r><w:t>Hello world!</w:t></w:r></w:p></w:body>
         </w:document>";

     using (Stream stream = part.GetStream())
     {
         byte[] buf = (new UTF8Encoding()).GetBytes(docXml);
         stream.Write(buf, 0, buf.Length);
     }
    }

Answer 1

I've tried to use the code You posted in the Edits section of Your question and it produces a corrupted file indeed. The issue seems to be associated with an invalid namespace You have specified in the docXml string:

http://schemas.openxmlformats.org /wordprocessingml/2006/main

that should be changed to:

http://schemas.openxmlformats.org/wordprocessingml/2006/main

(without a whitespace in the middle). This should produce a file that can be opened without error messages.

The first XML You posted, however, has got a different structure and requires a different solution. I'll try to find a solution and update this answer with some information about it.

UPDATE

The first XML You've posted (with w:wordDocument as main node) is similar to the one described in this article and seems to be a Word 2003 XML format rather than Open XML: http://blogs.msdn.com/b/brian_jones/archive/2005/07/05/intro-to-word-xml-part-1-simple-word-document.aspx.

To make it work, You can save the string in an xml file:

File.WriteAllText("C:\\data\\newFileName.xml", docXml);

Then, You can open the file with Word and it should be able to read it without issues. However, in this case You will probably have to select Open with... option and manually choose Word to open the file, which is quite inconvenient.

According to this article (https://msdn.microsoft.com/en-us/library/office/aa223584%28v=office.11%29.aspx), however, You should be able to save the XML as doc file as well, so You can save the XML string like this:

File.WriteAllText("C:\\data\\newFileName.doc", docXml);

For the XML You've posted, this should produce a doc file that can be opened by Word without issues.
