I'm trying to iterate through a Word document and extract the footnotes out of it, with a reference to where they belong in the paragraph.
I'm not sure how to do this.
I saw that in order to get all the footnotes I can do something like this:
FootnotesPart footnotesPart = doc.MainDocumentPart.FootnotesPart;
if (footnotesPart != null)
{
IEnumerable<Footnote> footnotes = footnotesPart.Footnotes.Elements<Footnote>();
foreach (var footnote in footnotes)
{
...
}
}
However, I don't know how to know where each footnote belongs in the paragraph.
I want, for instance, to take a footnote, and put it in brackets inside the text where it was a footnote before.
How do I do this?
You have to locate the FootnoteReference
element with the same Id as the FootNote
. This will give you the Run
element, where the footnote is located.
Sample code:
FootnotesPart footnotesPart = doc.MainDocumentPart.FootnotesPart;
if (footnotesPart != null)
{
var footnotes = footnotesPart.Footnotes.Elements<Footnote>();
var references = doc.MainDocumentPart.Document.Body.Descendants<FootnoteReference>().ToArray();
foreach (var footnote in footnotes)
{
long id = footnote.Id;
var reference = references.Where(fr => (long)fr.Id == id).FirstOrDefault();
if (reference != null)
{
Run run = reference.Parent as Run;
reference.Remove();
var fnText = string.Join("", footnote.Descendants<Run>().SelectMany(r => r.Elements<Text>()).Select(t => t.Text)).Trim();
run.Parent.InsertAfter(new Run(new Text("(" + fnText + ")")), run);
}
}
}
doc.MainDocumentPart.Document.Save();
doc.Close();
