Replace bookmark text in Word file using Open XML SDK

Question

I assume v2.0 is better... they have some nice \"how to:...\" examples but bookmarks don\'t seem to act as obviously as say a Table... a bookmark is defined by two

Answer 1

I just figured this out 10 minutes ago so forgive the hackish nature of the code.

First I wrote a helper recursive helper function to find all the bookmarks:

private static Dictionary FindBookmarks(OpenXmlElement documentPart, Dictionary results = null, Dictionary unmatched = null )
{
    results = results ?? new Dictionary();
    unmatched = unmatched ?? new Dictionary();

    foreach (var child in documentPart.Elements())
    {
        if (child is BookmarkStart)
        {
            var bStart = child as BookmarkStart;
            unmatched.Add(bStart.Id, bStart.Name);
        }

        if (child is BookmarkEnd)
        {
            var bEnd = child as BookmarkEnd;
            foreach (var orphanName in unmatched)
            {
                if (bEnd.Id == orphanName.Key)
                    results.Add(orphanName.Value, bEnd);
            }
        }

        FindBookmarks(child, results, unmatched);
    }

    return results;
}

That returns me a Dictionary that I can use to part through my replacement list and add the text after the bookmark:

var bookMarks = FindBookmarks(doc.MainDocumentPart.Document);

foreach( var end in bookMarks )
{
    var textElement = new Text("asdfasdf");
    var runElement = new Run(textElement);

    end.Value.InsertAfterSelf(runElement);
}

From what I can tell inserting into and replacing the bookmarks looks harder. When I used InsertAt instead of InsertIntoSelf I got: "Non-composite elements do not have child elements." YMMV
