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

Here's what I ended up with - not 100% perfect but works for simple bookmarks and simple text to insert:

private void FillBookmarksUsingOpenXml(string sourceDoc, string destDoc, Dictionary bookmarkData)
    {
        string wordmlNamespace = "http://schemas.openxmlformats.org/wordprocessingml/2006/main";
        // Make a copy of the template file.
        File.Copy(sourceDoc, destDoc, true);

        //Open the document as an Open XML package and extract the main document part.
        using (WordprocessingDocument wordPackage = WordprocessingDocument.Open(destDoc, true))
        {
            MainDocumentPart part = wordPackage.MainDocumentPart;

            //Setup the namespace manager so you can perform XPath queries 
            //to search for bookmarks in the part.
            NameTable nt = new NameTable();
            XmlNamespaceManager nsManager = new XmlNamespaceManager(nt);
            nsManager.AddNamespace("w", wordmlNamespace);

            //Load the part's XML into an XmlDocument instance.
            XmlDocument xmlDoc = new XmlDocument(nt);
            xmlDoc.Load(part.GetStream());

            //Iterate through the bookmarks.
            foreach (KeyValuePair bookmarkDataVal in bookmarkData)
            {
                var bookmarks = from bm in part.Document.Body.Descendants()
                          select bm;

                foreach (var bookmark in bookmarks)
                {
                    if (bookmark.Name == bookmarkDataVal.Key)
                    {
                        Run bookmarkText = bookmark.NextSibling();
                        if (bookmarkText != null)  // if the bookmark has text replace it
                        {
                            bookmarkText.GetFirstChild().Text = bookmarkDataVal.Value;
                        }
                        else  // otherwise append new text immediately after it
                        {
                            var parent = bookmark.Parent;   // bookmark's parent element

                            Text text = new Text(bookmarkDataVal.Value);
                            Run run = new Run(new RunProperties());
                            run.Append(text);
                            // insert after bookmark parent
                            parent.Append(run);
                        }

                        //bk.Remove();    // we don't want the bookmark anymore
                    }
                }
            }

            //Write the changes back to the document part.
            xmlDoc.Save(wordPackage.MainDocumentPart.GetStream(FileMode.Create));
        }
    }
