将多个word文档合并为一个Open Xml [英] Merge multiple word documents into one Open Xml

问题描述

我有大约 10 个 word 文档，这些文档是使用 open xml 和其他东西生成的.现在我想创建另一个word文档，我想将它们一个一个地加入到这个新创建的文档中.我希望使用 open xml，任何提示都是可观的.下面是我的代码:

I have around 10 word documents which I generate using open xml and other stuff. Now I would like to create another word document and one by one I would like to join them into this newly created document. I wish to use open xml, any hint would be appreciable. Below is my code:

 private void CreateSampleWordDocument()
    {
        //string sourceFile = Path.Combine("D:\GeneralLetter.dot");
        //string destinationFile = Path.Combine("D:\New.doc");
        string sourceFile = Path.Combine("D:\GeneralWelcomeLetter.docx");
        string destinationFile = Path.Combine("D:\New.docx");
        try
        {
            // Create a copy of the template file and open the copy
            //File.Copy(sourceFile, destinationFile, true);
            using (WordprocessingDocument document = WordprocessingDocument.Open(destinationFile, true))
            {
                // Change the document type to Document
                document.ChangeDocumentType(DocumentFormat.OpenXml.WordprocessingDocumentType.Document);
                //Get the Main Part of the document
                MainDocumentPart mainPart = document.MainDocumentPart;
                mainPart.Document.Save();
            }
        }
        catch
        {
        }
    }

更新(使用 AltChunks):

using (WordprocessingDocument myDoc = WordprocessingDocument.Open("D:\Test.docx", true))
        {
            string altChunkId = "AltChunkId" + DateTime.Now.Ticks.ToString().Substring(0, 2) ;
            MainDocumentPart mainPart = myDoc.MainDocumentPart;
            AlternativeFormatImportPart chunk = mainPart.AddAlternativeFormatImportPart(
                AlternativeFormatImportPartType.WordprocessingML, altChunkId);
            using (FileStream fileStream = File.Open("D:\Test1.docx", FileMode.Open))
                chunk.FeedData(fileStream);
            AltChunk altChunk = new AltChunk();
            altChunk.Id = altChunkId;
            mainPart.Document
                .Body
                .InsertAfter(altChunk, mainPart.Document.Body.Elements<Paragraph>().Last());
            mainPart.Document.Save();
        } 

当我使用多个文件时，为什么这段代码会覆盖最后一个文件的内容?更新 2:

Why this code overwrites the content of the last file when I use multiple files? Update 2:

 using (WordprocessingDocument myDoc = WordprocessingDocument.Open("D:\Test.docx", true))
        {

            MainDocumentPart mainPart = myDoc.MainDocumentPart;
            string altChunkId = "AltChunkId" + DateTime.Now.Ticks.ToString().Substring(0, 3);
            AlternativeFormatImportPart chunk = mainPart.AddAlternativeFormatImportPart(AlternativeFormatImportPartType.WordprocessingML, altChunkId);
            using (FileStream fileStream = File.Open("d:\Test1.docx", FileMode.Open))
            {
                chunk.FeedData(fileStream);
                AltChunk altChunk = new AltChunk();
                altChunk.Id = altChunkId;
                mainPart.Document
                    .Body
                    .InsertAfter(altChunk, mainPart.Document.Body
                    .Elements<Paragraph>().Last());
                mainPart.Document.Save();
            }
            using (FileStream fileStream = File.Open("d:\Test2.docx", FileMode.Open))
            {
                chunk.FeedData(fileStream);
                AltChunk altChunk = new AltChunk();
                altChunk.Id = altChunkId;
                mainPart.Document
                    .Body
                    .InsertAfter(altChunk, mainPart.Document.Body
                    .Elements<Paragraph>().Last());
            }
            using (FileStream fileStream = File.Open("d:\Test3.docx", FileMode.Open))
            {
                chunk.FeedData(fileStream);
                AltChunk altChunk = new AltChunk();
                altChunk.Id = altChunkId;
                mainPart.Document
                    .Body
                    .InsertAfter(altChunk, mainPart.Document.Body
                    .Elements<Paragraph>().Last());
            } 
        }

这段代码两次附加了 Test2 数据，也代替了 Test1 数据.意味着我得到:

This code is appending the Test2 data twice, in place of Test1 data as well. Means I get:

Test
Test2
Test2

而不是:

Test
Test1
Test2

推荐答案

仅使用 openXML SDK，您可以使用 AltChunk 元素将多个文档合并为一个.

Using openXML SDK only, you can use AltChunk element to merge the multiple document into one.

这个链接the-easy-way-to-assemble-multiple-word-documents 和这个 如何使用 altChunk 进行文档组装 提供了一些示例.

This link the-easy-way-to-assemble-multiple-word-documents and this one How to Use altChunk for Document Assembly provide some samples.

根据您在更新的问题 (update#1) 中使用 altchunk 的代码，这里是我测试过的 VB.Net 代码，它的工作原理很有魅力对我来说:

Based on your code that uses altchunk in the updated question (update#1), here is the VB.Net code I have tested and that works like a charm for me:

Using myDoc = DocumentFormat.OpenXml.Packaging.WordprocessingDocument.Open("D:\Test.docx", True)
        Dim altChunkId = "AltChunkId" + DateTime.Now.Ticks.ToString().Substring(0, 2)
        Dim mainPart = myDoc.MainDocumentPart
        Dim chunk = mainPart.AddAlternativeFormatImportPart(
            DocumentFormat.OpenXml.Packaging.AlternativeFormatImportPartType.WordprocessingML, altChunkId)
        Using fileStream As IO.FileStream = IO.File.Open("D:\Test1.docx", IO.FileMode.Open)
            chunk.FeedData(fileStream)
        End Using
        Dim 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()
End Using

第二期(update#2)

此代码将 Test2 数据附加两次，代替 Test1 数据作为嗯.

This code is appending the Test2 data twice, in place of Test1 data as well.

与 altchunkid 相关.

对于要在主文档中合并的每个文档，您需要:

For each document you want to merge in the main document, you need to:

1. 在 mainDocumentPart 中添加一个 AlternativeFormatImportPart，其中 Id 必须是唯一的. 此元素包含插入的数据
2. 在正文中添加一个 Altchunk 元素，您可以在其中设置 id 以引用之前的 AlternativeFormatImportPart.

1. add an AlternativeFormatImportPart in the mainDocumentPart with an Id which must to be unique. This element contains the Inserted data
2. add in the body an Altchunk element in which you set the id to reference the previous AlternativeFormatImportPart.

在您的代码中，您对所有 AltChunks 使用相同的 Id.这就是为什么您会多次看到相同的文本.

In your code, you are using the same Id for all the AltChunks. It's why you see many time the same text.

我不确定 altchunkid 在您的代码中是否是唯一的:string altChunkId = "AltChunkId" + DateTime.Now.Ticks.ToString().Substring(0, 2);

I am not sure the altchunkid will be unique with your code: string altChunkId = "AltChunkId" + DateTime.Now.Ticks.ToString().Substring(0, 2);

如果您不需要设置特定值，我建议您在添加 AlternativeFormatImportPart 时不要显式设置 AltChunkId.相反，您会像这样得到一个由 SDK 生成的:

If you don't need to set a specific value, I recommend you to not set explicitly the AltChunkId when you add the AlternativeFormatImportPart. Instead, you get one generated by the SDK like this:

VB.Net

Dim chunk As AlternativeFormatImportPart = mainPart.AddAlternativeFormatImportPart(DocumentFormat.OpenXml.Packaging.AlternativeFormatImportPartType.WordprocessingML)
Dim altchunkid As String = mainPart.GetIdOfPart(chunk)

C#

AlternativeFormatImportPart chunk = mainPart.AddAlternativeFormatImportPart(DocumentFormat.OpenXml.Packaging.AlternativeFormatImportPartType.WordprocessingML);
string altchunkid = mainPart.GetIdOfPart(chunk);
