使用SDK 2.0包含.docx文件时Altchunks的问题 [英] Problem with Altchunks when including .docx file using SDK 2.0

问题描述

您好，我正在尝试使用OpenXML SDK 2.0使用altchunks将两个.docx文档合并在一起。我的第一个文档包含一个或多个书签，我想将第二个文档插入书签后的第一个文档。这似乎不是一个非常复杂的任务，但是当我在生成的文档上运行验证器时，我总是会收到以下错误：

错误1
描述：关系'http：//由属性'id'引用的schemas.openxmlformats.org/officeDocument/2006
/ relationships / aFChunk'的类型不正确。它的类型应该是'http://schemas.openxmlformats.org/officeDocument/2006/afChunk'。
路径：/ w：document [1] / w：body [1] / w： altChunk [1]
部分：/word/document.xml
------------------------------ -------------

任何人都可以帮忙吗？以下是我的测试代码：

Hello,

I am trying to use the OpenXML SDK 2.0 to merge two .docx documents together using altchunks.  My first document contains one or more bookmarks, I would like to insert the second document into the first right after the bookmark.  This doesn't seem like a very complicated task, but when I run the validator on the generated document I always get the following error:

Error 1
Description: Relationship 'http://schemas.openxmlformats.org/officeDocument/2006
/relationships/aFChunk' referenced by attribute 'id' has incorrect type. Its typ
e should be 'http://schemas.openxmlformats.org/officeDocument/2006/afChunk'.
Path: /w:document[1]/w:body[1]/w:altChunk[1]
Part: /word/document.xml

Can anyone help?  Below is my test code:

                    var bar = mainPart.Document.Descendants().Where(s => s.Id.ToString().Equals(sBmkId));

                    BookmarkEnd be = bar.First();

                    var parent = be.Parent;

                    string sChunkId = "AltChunkId" + iChunkId.ToString();

                int count = 0;
                foreach (ValidationErrorInfo error in validator.Validate(WordprocessingDocument.Open(docxOutputFile, true)))

                    count++;
                    Console.WriteLine("Error " + count);

                }
                if (count == 0)
                    Console.WriteLine("IT WORKED!");
                Console.ReadKey();
            }
            catch (Exception ex)

        }
    }

推荐答案

可以忽略该验证错误，因为Word能够处理aFChunk或afChunk。运行代码并打开文档时会发生什么？ Word是否适当地合并了altChunk？

That validation error can be ignored, since Word is able to handle either aFChunk or afChunk. What happens when you run your code and open your document? Does Word merge the altChunk appropriately?
