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

The accepted answer and some of the others make assumptions about where the bookmarks are in the document structure. Here's my C# code, which can deal with replacing bookmarks that stretch across multiple paragraphs and correctly replace bookmarks that do not start and end at paragraph boundaries. Still not perfect, but closer... hope it's useful. Edit if you find more ways to improve it!

    private static void ReplaceBookmarkParagraphs(MainDocumentPart doc, string bookmark, IEnumerable paras) {
        var start = doc.Document.Descendants().Where(x => x.Name == bookmark).First();
        var end = doc.Document.Descendants().Where(x => x.Id.Value == start.Id.Value).First();
        OpenXmlElement current = start;
        var done = false;

        while ( !done && current != null ) {
            OpenXmlElement next;
            next = current.NextSibling();

            if ( next == null ) {
                var parentNext = current.Parent.NextSibling();
                while ( !parentNext.HasChildren ) {
                    var toRemove = parentNext;
                    parentNext = parentNext.NextSibling();
                    toRemove.Remove();
                }
                next = current.Parent.NextSibling().FirstChild;

                current.Parent.Remove();
            }

            if ( next is BookmarkEnd ) {
                BookmarkEnd maybeEnd = (BookmarkEnd)next;
                if ( maybeEnd.Id.Value == start.Id.Value ) {
                    done = true;
                }
            }
            if ( current != start ) {
                current.Remove();
            }

            current = next;
        }

        foreach ( var p in paras ) {
            end.Parent.InsertBeforeSelf(p);
        }
    }
