将多个word文档合并为一个Open Xml

标签: c# merge openxml docx openxml-sdk

我有大约10个word文档,我使用open xml和其他东西生成。 现在我想创建另一个word文档,我想逐个加入到这个新创建的文档中。 我希望使用open xml,任何提示都会很明显。 以下是我的代码:

 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();
        } 

为什么在使用多个文件时此代码会覆盖最后一个文件的内容? 更新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());
            } 
        }

此代码将Test2数据附加两次,代替Test1数据。 意思是我得到了:

Test
Test2
Test2

而不是:

Test
Test1
Test2

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

此链接the-easy-way-to-assemble-multiple-word-documents和此How to Use altChunk for Document Assembly提供了一些示例。

根据您在更新的问题(更新#1)中使用altchunk的代码,这是我测试过的VB.Net代码,对我来说就像一个魅力:

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

第二个问题(更新#2)

  

此代码将Test2数据附加两次,代替Test1数据   好。

altchunkid有关。

对于要在主文档中合并的每个文档,您需要:

  1. AlternativeFormatImportPart中添加mainDocumentPartId 必须是唯一的。此元素包含已插入的数据
  2. 在正文中添加Altchunk元素,您可以在其中设置id以引用之前的AlternativeFormatImportPart
  3. 在您的代码中,您对所有AltChunks使用相同的ID。这就是为什么你会看到很多时间相同的文字。

    我不确定altchunkid在您的代码中是唯一的: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AltChunkId时不要明确设置AlternativeFormatImportPart。相反,你会得到一个由SDK生成的:

    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);

有一个很好的封装API(Document Builder 2.2)围绕open xml专门设计用于合并文档,可灵活选择要合并的段落等。您可以从here下载它(更新:移动到{{ 3}})。

有关如何使用它的文档和屏幕演员是github

更新:代码示例

 var sources = new List<Source>();
 //Document Streams (File Streams) of the documents to be merged.
 foreach (var stream in documentstreams)
 {
        var tempms = new MemoryStream();
        stream.CopyTo(tempms);
        sources.Add(new Source(new WmlDocument(stream.Length.ToString(), tempms), true));
 }

  var mergedDoc = DocumentBuilder.BuildDocument(sources);
  mergedDoc.SaveAs(@"C:\TargetFilePath");

类型SourceWmlDocument来自Document Builder API。

如果您选择:

,您甚至可以直接添加文件路径
sources.Add(new Source(new WmlDocument(@"C:\FileToBeMerged1.docx"));
sources.Add(new Source(new WmlDocument(@"C:\FileToBeMerged2.docx"));

AltChunkDocument Builder合并文档的方法之间找到here - 有助于根据要求进行选择。

您也可以使用Nice Comparison库来合并文档,但我更喜欢使用Document Builder来合并文档。

希望这有帮助。

易于在C#中使用:

using System;
using System.IO;
using System.Linq;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Wordprocessing;

namespace WordMergeProject
{
    public class Program
    {
        private static void Main(string[] args)
        {
            byte[] word1 = File.ReadAllBytes(@"..\..\word1.docx");
            byte[] word2 = File.ReadAllBytes(@"..\..\word2.docx");

            byte[] result = Merge(word1, word2);

            File.WriteAllBytes(@"..\..\word3.docx", result);
        }

        private static byte[] Merge(byte[] dest, byte[] src)
        {
            string altChunkId = "AltChunkId" + DateTime.Now.Ticks.ToString();

            var memoryStreamDest = new MemoryStream();
            memoryStreamDest.Write(dest, 0, dest.Length);
            memoryStreamDest.Seek(0, SeekOrigin.Begin);

                altPart.FeedData(memoryStreamSrc);
                var altChunk = new AltChunk();
                altChunk.Id = altChunkId;
                              OpenXmlElement lastElem = mainPart.Document.Body.Elements<AltChunk>().LastOrDefault();
            if(lastElem == null)
            {
                lastElem = mainPart.Document.Body.Elements<Paragraph>().Last();
            }


            //Page Brake einfügen
            Paragraph pageBreakP = new Paragraph();
            Run pageBreakR = new Run();
            Break pageBreakBr = new Break() { Type = BreakValues.Page };

            pageBreakP.Append(pageBreakR);
            pageBreakR.Append(pageBreakBr);                

            return memoryStreamDest.ToArray();
        }
    }
}

这些答案中唯一缺少的是for循环。

对于只想复制/粘贴它的人:

void MergeInNewFile(string resultFile, IList<string> filenames)
{
    using (WordprocessingDocument document = WordprocessingDocument.Create(resultFile, WordprocessingDocumentType.Document))
    {
        MainDocumentPart mainPart = document.AddMainDocumentPart();
        mainPart.Document = new Document(new Body());

        foreach (string filename in filenames)
        {
            AlternativeFormatImportPart chunk = mainPart.AddAlternativeFormatImportPart(AlternativeFormatImportPartType.WordprocessingML);
            string altChunkId = mainPart.GetIdOfPart(chunk);

            using (FileStream fileStream = File.Open(filename, FileMode.Open))
            {
                chunk.FeedData(fileStream);
            }

            AltChunk altChunk = new AltChunk { Id = altChunkId };
            mainPart.Document.Body.AppendChild(altChunk);
        }

        mainPart.Document.Save();
    }
}
