使用 OpenXml 和 C# 复制 Word 文档
我正在使用 Word 和 OpenXml 在 C# ASP.NET Web 应用程序中提供邮件合并功能:
1) 上传一个文档,其中包含许多预定义的字符串以供替换。
2) 使用 OpenXML SDK 2.0 打开 Word 文档,以字符串形式获取 mainDocumentPart,并使用 Regex 执行替换。
3) 然后,我使用 OpenXML 创建一个新文档,添加一个新的 mainDocumentPart 并将替换产生的字符串插入到该 mainDocumentPart 中。
但是,所有格式/样式等都会在新文档中丢失。
我猜我可以单独复制并添加样式、定义、注释部分等来模仿原始文档。
但是,是否有一种使用 Open XML 复制文档的方法,允许我在新副本上执行替换?
谢谢。
I am using Word and OpenXml to provide mail merge functionality in a C# ASP.NET web application:
1) A document is uploaded with a number of pre-defined strings for substitution.
2) Using the OpenXML SDK 2.0 I open the Word document, get the mainDocumentPart as a string and perform the substitution using Regex.
3) I then create a new document using OpenXML, add a new mainDocumentPart and insert the string resulting from the substitution into this mainDocumentPart.
However, all formatting/styles etc. are lost in the new document.
I'm guessing I can copy and add the Style, Definitions, Comment parts etc.. individually to mimic the orginal document.
However is there a method using Open XML to duplicate a document allowing me to perform the substitutions on the new copy?
Thanks.

这段代码应该将现有文档的所有部分复制到新文档中。
This piece of code should copy all parts from an existing document to a new one.
我赞成使用内容控制建议。 使用它们来标记文档中要执行替换的区域是迄今为止最简单的方法。
至于复制文档(并保留整个文档内容、样式等)相对容易:
实际上使用 LINQ 查找内容控件是小菜一碟。 以下示例查找所有简单文本内容控件(类型为 SdtRun):

元素可能尚不存在,但正在创建它们很简单:希望对某人有帮助。 :D
I second the use of Content Controls recommendation. Using them to mark up the areas of your document where you want to perform substitution is by far the easiest way to do it.
As for duplicating the document (and retaining the entire document contents, styles and all) it's relatively easy:
Actually finding the content controls is a piece of cake using LINQ. The following example finds all the Simple Text content controls (which are typed as SdtRun):
The
<Run>
and<Text>
elements may not already exist but creating them is a simple as:Hope that helps someone. :D
在将许多有用的功能添加到 Open XML SDK 之前就提出了最初的问题。 如今,如果您已经打开了
WordprocessingDocument
,您只需克隆原始文档并对该克隆执行任何转换即可。您还可以克隆
Stream
或Package
。 总的来说,您有以下选择:查看 Open XML SDK 文档以获取有关这些方法的详细信息。
尽管如此,如果您尚未打开
WordprocessingDocument
,至少还有更快的方法来复制或克隆文档。 我在 克隆 Office Open XML 文档的最有效方法。The original question was asked before a number of helpful features were added to the Open XML SDK. Nowadays, if you already have an opened
WordprocessingDocument
, you would simply clone the original document and perform whatever transformation on that clone.You can also clone on a
Stream
orPackage
. Overall, you have the following options:Have a look at the Open XML SDK documentation for details on those methods.
Having said that, if you have not yet opened the
WordprocessingDocument
, there are at least faster ways to duplicate, or clone, the document. I've demonstrated this in my answer on the most efficient way to clone Office Open XML documents.我做了一些非常类似的事情,但我不使用文本替换字符串,而是使用文字内容控件。 我已在以下博客文章 SharePoint 和 Open 中记录了一些详细信息xml。 该技术并非特定于 SharePoint。 您可以在纯 ASP.NET 或其他应用程序中重用该模式。
另外,我强烈建议您查看 Eric White 的博客,了解有关 Open Xml 的提示、技巧和技术。 具体来说,请查看 Open Xml 帖子的内存操作,以及 Word 内容控件 帖子。 我想从长远来看你会发现这些更有帮助。
希望这可以帮助。
I have done some very similar things, but instead of using text substitution strings, I use Word Content Controls. I have documented some of the details in the following blog post, SharePoint and Open Xml. The technique is not specific to SharePoint. You could reuse the pattern in pure ASP.NET or other applications.
Also, I would STRONGLY encourage you to review Eric White's Blog for tips, tricks and techniques regarding Open Xml. Specifically, check out the in-memory manipulation of Open Xml post, and the Word content controls posts. I think you'll find these much more helpful in the long run.
Hope this helps.
作为上述内容的补充; 也许更有用的是查找已标记的内容控件(使用单词 GUI)。 我最近编写了一些软件,用于填充文档模板,其中包含带有附加标签的内容控件。 找到它们只是上述 LINQ 查询的扩展:
我从其他地方获得了这段代码,但目前不记得在哪里; 完全归功于他们。
该查询只是创建一个匿名类型的 IEnumerable,其中包含内容控件及其关联的标记作为属性。 便利!
As an addenda to the above; what's perhaps more useful is finding content controls that have been tagged (using the word GUI). I recently wrote some software that populated document templates that contained content controls with tags attached. To find them is just an extension of the above LINQ query:
I got this code from elsewhere but cannot remember where at the moment; full credit goes to them.
The query just creates an IEnumerable of an anonymous type that contains the content control and its associated tag as properties. Handy!
当您通过将扩展名更改为 zip 并打开它来查看 openxml 文档时,您会看到该 word 子文件夹包含一个 _rels 文件夹,其中列出了所有关系。 这些关系指向你提到的部分(风格......)。 实际上您需要这些部分,因为它们包含格式的定义。 因此,不复制它们将导致新文档使用 normal.dot 文件中定义的格式,而不是原始文档中定义的格式。 所以我认为你必须复制它们。
When you look at an openxml document by changing the extension to zip and opening it you see that that word subfolder contains a _rels folder where all the relations are listed. These relations point to the parts you mentioned (style ...). Actually you need these parts because they contain the definition of the formatting. So not copying them will cause the new document to use the formatting defined in the normal.dot file and not the one defined in the original document. So I think you have to copy them.
