Descendants gets zero elements in Word doc

Question

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() cal

Answer 1

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 ...

With a regular Word doc, looking at

doc.MainDocumentPart.Document.Body.InnerXml

the value starts with:

  
    Hello World!

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

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

Update:

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

string strDocumentXml = newWordContent.DocumentElement.InnerXml;

but instead this is the correct data:

string strDocumentXml = newWordContent.DocumentElement.FirstChild.OuterXml;

Inspection with the debugger of:

doc.MainDocumentPart.Document.Body.InnerXml

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

Side note:

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