后代在Word文档中获取零个元素 [英] Descendants<T> gets zero elements in Word doc

问题描述

我在更新Word文档中的超链接时遇到问题(Q 如何在Word文档中更新正文和超链接)，并且正在放大Descendants<T>()调用，但无法正常工作.这是我的代码:

I am having trouble updating a Hyperlink in a Word doc (Q How to update the body and a hyperlink in a Word doc ) and am zooming in on the Descendants<T>() call not working. Here is my code:

using DocumentFormat.OpenXml.Packaging;      //from NuGet ClosedXML
using DocumentFormat.OpenXml.Wordprocessing; //from NuGet ClosedXML

WordprocessingDocument doc = WordprocessingDocument.Open(...filename..., true);
MainDocumentPart mainPart = doc.MainDocumentPart;
IEnumerable<Hyperlink> hLinks = mainPart.Document.Body.Descendants<Hyperlink>();

因为mainPart获得了一个值，所以文档被打开，确定.但是hLinks没有任何元素.如果我在Word中打开Word文档，则会显示一个超链接并且可以正常工作.

The doc is opened OK because mainPart gets a value. But hLinks has no elements. If I open the Word doc in Word, a hyperlink is present and working.

在立即窗口中，我看到以下值:

In the Immediate Window I see the following values:

mainPart.Document.Body
-->
{DocumentFormat.OpenXml.Wordprocessing.Body}
    ChildElements: {DocumentFormat.OpenXml.OpenXmlChildElements}
    ExtendedAttributes: {DocumentFormat.OpenXml.EmptyEnumerable<DocumentFormat.OpenXml.OpenXmlAttribute>}
    FirstChild: {DocumentFormat.OpenXml.OpenXmlUnknownElement}
    HasAttributes: false
    HasChildren: true
    InnerText: "
       lots of data, e.g:
    ...<w:t>100</w:t>...

mainPart.Document.Body.Descendants<Text>().First()
-->
Exception: "Sequence contains no elements"

如果我什至找不到文本部分，应该如何查找和替换超链接?

If I cannot even find the text parts, how should I ever find and replace the hyperlink?

推荐答案

我的Word文档似乎有问题；它是用工具生成的.使用用Word创建的另一个Word文档进行测试可获得更好的结果.我正在努力...

Something seems to be wrong with my Word doc; it was generated with a tool. Testing with another Word doc, created with Word, gives better results. I am working on it ...

使用普通的Word文档，查看

With a regular Word doc, looking at

doc.MainDocumentPart.Document.Body.InnerXml

值开头:

<w:p w:rsidR=\"00455325\" w:rsidRDefault=\"00341915\" 
  xmlns:w=\"http://schemas.openxmlformats.org/wordprocessingml/2006/main\">
  <w:r>
    <w:t>Hello World!

但使用我正在测试的doc一词，它来自我自己制作的工具:

but with the word doc I am testing with, which comes from a tool I myself made:

<w:body xmlns:w=\"http://schemas.openxmlforma...

这解释了很多. 我将不得不修复我的工具:-)

This explains a lot. I will have to fix my tool :-)

更新:

解决方法是，这没有提供要插入Word Doc的数据的正确部分:

The fix was that this did not give the correct part of data to insert in the Word Doc:

string strDocumentXml = newWordContent.DocumentElement.InnerXml;

但这是正确的数据:

string strDocumentXml = newWordContent.DocumentElement.FirstChild.OuterXml;

使用以下调试器进行检查:

Inspection with the debugger of:

doc.MainDocumentPart.Document.Body.InnerXml

如上所述，

确认.现在，后代"调用将返回预期的数据，并且更新超链接有效.

as mentioned above, confirmed it. The Descendants call now returns the expected data, and updating the hyperlink works.

旁注:

我显然已经修复了我的应用程序中的一个错误，但是除了更新超链接之外，该应用程序之前还可以正常运行，并且存在该错误:-)

I clearly fixed a bug in my app, but, apart from updating the hyperlink, the app worked perfectly OK before, with that bug :-)
