How to Add Bookmarks to All Paragraphs and Retrieve Their Contents in .NET Core Word document?

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 add bookmarks to all paragraphs and retrieve their contents in a Word document using C#.

Overview of the logic to add bookmarks to all paragraph and retrieve content:

• Find all the paragraphs using FindAllItemsByProperty.
• Add a bookmark around each non-empty paragraph.
• Print the bookmark names along with their corresponding content.
• Iterate through all the bookmarks in a document
• Retrieve each bookmark’s name and its content.
• Save each paragraph as a separate Word document.

Steps to add bookmarks to all paragraphs and retrieve their contents in Word document:

1. Create a new .NET Core console application project.
   
   
2. Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your project from NuGet.org.
   
   

3. Include the following namespaces in the Program.cs file.
   C#

using Syncfusion.DocIO.DLS;
using Syncfusion.DocIO;

4. Use the following code example to add bookmarks to all paragraphs and retrieve their contents in Word document.
   C#

// Load the existing Word document
WordDocument document = new WordDocument(Path.GetFullPath("Data/Input.docx"));
// Retrieve all paragraph entities in the document
List<Entity> paragraphsToInsertBookmarks = document.FindAllItemsByProperty(EntityType.Paragraph, null, null);
foreach (Entity entity in paragraphsToInsertBookmarks)
{
    // Cast the entity to a paragraph
    WParagraph currentPara = entity as WParagraph;
    // Skip the paragraph if it is empty
    if (currentPara.Text != string.Empty)
    {
        // Create a unique bookmark name using a GUID
        string bookmarkName = "Bookmark" + Guid.NewGuid();
        // Insert a bookmark start at the beginning of the paragraph
        currentPara.ChildEntities.Insert(0, new BookmarkStart(document, bookmarkName));
        // Insert a bookmark end at the end of the paragraph
        currentPara.AppendBookmarkEnd(bookmarkName);
        // Print the bookmark name and the paragraph text to the console
        Console.WriteLine("Corresponding Bookmark : " + bookmarkName);
        Console.WriteLine("Content : " + currentPara.Text + "\n");
    }
}
// Save each bookmarked paragraph as a separate document
SaveBookmarksAsSeparateDocuments(document);
// Close the Word document
document.Close();
Console.ReadLine();

5. Use the following code example to retrieve all bookmark contents and save each paragraph as a separate Word document.
   C#

private static void SaveBookmarksAsSeparateDocuments(WordDocument document)
{
    int paragraphCount = 0;
    // Iterate through each bookmark
    foreach (Bookmark currentBookmark in document.Bookmarks)
    {
        // Create navigator to move to the current bookmark
        BookmarksNavigator bookmarkNavigator = new BookmarksNavigator(document);
        bookmarkNavigator.MoveToBookmark(currentBookmark.Name);
        // Extract the content inside the bookmark as a temporary Word document
        WordDocument tempDoc = bookmarkNavigator.GetContent().GetAsWordDocument();
        // Save the Word document.
        tempDoc.Save(Path.GetFullPath("../../../Output/Output_" + paragraphCount + ".docx"));
        // Close the temporary document.
        tempDoc.Close();
        paragraphCount++;
    }
}
