So up until recently this code worked, and then the users changed the format of the headers.
I am using C# and OpenXML to edit the term [Sample Client] out of a header and replacing it with an Image. This has worked in the past, and actually works with some of the headers, but not others. I can't figure out why. The error I get is "Cannot insert the OpenXmlElement "newChild" because it is part of a tree".
It fails on the line:
textPlaceHolder.Parent.InsertAfter<DocumentFormat.OpenXml.Wordprocessing.Drawing>(element, textPlaceHolder);
I have found some answers mentioning that I have to use CloneNode, but I am not sure how to implement that, or why. I could use some assistance.
Sorry for the terrible code.
