Syncfusion; Essential; DocIO is a .NET Word library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can find text and add bookmarks in Word document using C#. You can achieve the requirement by following these steps: Open the template Word document. Add a bookmark to the searched text. Find all bookmarks in the Word document using the FindAllItemsByProperty API. Iterate through the bookmarks and get the content from each bookmark. Steps to find text and add bookmarks in Word document: Create a new .NET Core console application project. Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your project from NuGet.org. Starting with v16.2.0.x, if you reference Syncfusion® assemblies from trial setup or from the NuGet feed, include a license key in your projects. Refer to the link to learn about generating and registering a Syncfusion® license key in your application to use the components without trail message. Include the following namespaces in Program.cs file C# using Syncfusion.DocIO.DLS; using Syncfusion.DocIO; Use the following code example to find text and add bookmarks in Word document. C# using (FileStream fileStream = new FileStream(Path.GetFullPath(@"Data/Template.docx"), FileMode.Open, FileAccess.ReadWrite)) { using (WordDocument document = new WordDocument(fileStream, FormatType.Automatic)) { // Define texts and corresponding bookmark names var textBookmarkPairs = new Dictionary<string, string> { { "they are considered one of the world's most loved animals.", "bkmk1" }, { "The table below lists the main characteristics the giant panda shares with bears and red pandas.", "bkmk2" }, { "Did you know that the giant panda may actually be a raccoon", "bkmk3" } }; // Add bookmarks to specified texts foreach (var pair in textBookmarkPairs) { AddBookmarkToText(document, pair.Key, pair.Value); } // Retrieve and display bookmark contents List<string> bookmarksContent = GetBookmarkContents(document); foreach (var content in bookmarksContent) { Console.WriteLine("Bookmark content: "); Console.WriteLine(content); } // Save the modified document using (FileStream outputStream = new FileStream(Path.GetFullPath(@"Output/Result.docx"), FileMode.Create, FileAccess.ReadWrite)) { document.Save(outputStream, FormatType.Docx); } } } Use the following code example to adds a bookmark to a specific text in the document. C# private static void AddBookmarkToText(WordDocument document, string searchText, string bookmarkName) { TextSelection textSelection = document.Find(searchText, false, true); if (textSelection != null) { WTextRange textRange = textSelection.GetAsOneRange(); int indexOfText = textRange.OwnerParagraph.Items.IndexOf(textRange); textRange.OwnerParagraph.Items.Insert(indexOfText, new BookmarkStart(document, bookmarkName)); textRange.OwnerParagraph.Items.Insert(indexOfText + 2, new BookmarkEnd(document, bookmarkName)); } } Use the following code example to retrieves all bookmark contents from the document. C# private static List<string> GetBookmarkContents(WordDocument document) { List<string> bookmarkContents = new List<string>(); foreach (Entity entity in document.FindAllItemsByProperty(EntityType.BookmarkStart, null, null)) { if (entity is BookmarkStart bookmarkStart) { var bookmarkNavigator = new BookmarksNavigator(document); bookmarkNavigator.MoveToBookmark(bookmarkStart.Name); WordDocumentPart part = bookmarkNavigator.GetContent(); WordDocument tempDoc = part.GetAsWordDocument(); bookmarkContents.Add(tempDoc.GetText()); tempDoc.Close(); tempDoc.Dispose(); part.Close(); } } return bookmarkContents; } You can download a complete working sample to find text and add bookmarks in Word document from the GitHub.

Syncfusion® Essential® DocIO is a .NET Word Library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can maintain list format of the source document to destination document after replacing bookmark content using C#. When replacing bookmark content in a Word document using the ReplaceContent method, the list format from the destination document is not applied to the replaced content. Instead, the replaced content retains the formatting from the source document. To maintain the list format from the destination document, you can retrieve the paragraph containing the replaced content after the replacement and apply the appropriate list formatting. Steps to maintain list format of the source document to destination document after replacing bookmark content: Create a new .NET Core console application project. Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your project from NuGet.org. Starting with v16.2.0.x, if you reference Syncfusion® assemblies from trial setup or from the NuGet feed, include a license key in your projects. Refer to the link to learn about generating and registering a Syncfusion® license key in your application to use the components without trail message. Include the following namespaces in Program.cs file C# using Syncfusion.DocIO.DLS; using Syncfusion.DocIO; Use the following code example to maintain list format of the source document to destination document after replacing bookmark content. C# using (FileStream destinationStream = new FileStream(Path.GetFullPath("Data/DestinationDocument.docx"), FileMode.Open, FileAccess.Read)) { //Open the destination Word document. using (WordDocument destinationDocument = new WordDocument(destinationStream, FormatType.Docx)) { using (FileStream srcStream = new FileStream(Path.GetFullPath(@"Data/SourceDocument.docx"), FileMode.Open, FileAccess.Read)) { //Open the source Word document. using (WordDocument srcDocument = new WordDocument(srcStream, FormatType.Docx)) { //Replace text "Text one" in the destination document with content from the bookmark "bkmk1" in the source document. ReplaceTextAndMaintainListFormat(destinationDocument, srcDocument, "Text one", "bkmk1"); //Replace text "Text two" in the destination document with content from the bookmark "bkmk2" in the source document. ReplaceTextAndMaintainListFormat(destinationDocument, srcDocument, "Text two", "bkmk2"); //Save the modified destination document to the output stream. using (FileStream output = new FileStream(Path.GetFullPath("Output/Output.docx"), FileMode.Create, FileAccess.Write)) { destinationDocument.Save(output, FormatType.Docx); } } } } } Use the following helper method to replace text in a Word document with bookmark content from another document. C# /// <summary> /// Replaces specific text in a Word document with bookmarked content from another document, maintaining formatting. /// </summary> private static void ReplaceTextAndMaintainListFormat(WordDocument destinationDocument, WordDocument sourceDocument, string tokenToFind, string textBookmark) { string bookmarkRef = textBookmark + "_bm"; // Find the text in the destination document where the bookmark start needs to be inserted.

WTextRange startText = start.GetAsOneRange(); WParagraph startParagraph = startText.OwnerParagraph; // Get the index of the selected text range in the paragraph. int index = startParagraph.Items.IndexOf(startText); // Remove the selected text at the identified index. startParagraph.Items.Remove(startText); // Create a BookmarkStart with a unique reference and insert it at the same index. BookmarkStart bookmarkStart = new BookmarkStart(destinationDocument, bookmarkRef); startParagraph.Items.Insert(index, bookmarkStart); // Append a BookmarkEnd with the same reference to mark the bookmark’s end. startParagraph.AppendBookmarkEnd(bookmarkRef); // Check if the specified bookmark exists in the source document. if (sourceDocument.Bookmarks.FindByName(textBookmark) != null) { // Move the navigator to the bookmark in the source document. BookmarksNavigator bookmarksNavigator = new BookmarksNavigator(sourceDocument); bookmarksNavigator.MoveToBookmark(textBookmark); // Extract the content within the bookmark. WordDocumentPart wordDocumentPart = bookmarksNavigator.GetContent(); // Move the navigator to the newly created bookmark in the destination document. bookmarksNavigator = new BookmarksNavigator(destinationDocument); bookmarksNavigator.MoveToBookmark(bookmarkRef); // Get the paragraph containing the bookmark start in the destination document. WParagraph destinationPara = bookmarksNavigator.CurrentBookmark.BookmarkStart.OwnerParagraph; // Store the list style, first-line indent, and left indent of the paragraph. string listStyleName = destinationPara.ListFormat.CustomStyleName; float firstLineIndent = destinationPara.ParagraphFormat.FirstLineIndent; float leftIndent = destinationPara.ParagraphFormat.LeftIndent; // Replace the bookmark content with the extracted content from the source document. bookmarksNavigator.ReplaceContent(wordDocumentPart); // Reapply the original list style and indent settings to the paragraph. destinationPara.ListFormat.ApplyStyle(listStyleName); destinationPara.ParagraphFormat.FirstLineIndent = firstLineIndent; destinationPara.ParagraphFormat.LeftIndent = leftIndent; } else { // If the bookmark is not found, replace the content with an empty string. BookmarksNavigator bookmarksNavigator = new BookmarksNavigator(destinationDocument); bookmarksNavigator.MoveToBookmark(bookmarkRef); bookmarksNavigator.ReplaceBookmarkContent(string.Empty, true); } } } You can download a complete working sample to maintain list format of the source document to destination document after replacing bookmark content from the GitHub.
