How to export Bookmarks content as HTML 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 export bookmark content as HTML in a Word document using C#.

To achieve this, we used the BookmarksNavigator, to extract the content and saved it as an HTML file.

Steps to export bookmark content as HTML in a 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 export bookmark content as HTML in a Word document.
   C#

using (FileStream inputStream = new FileStream(Path.GetFullPath(@"Data/Input.docx"), FileMode.Open, FileAccess.Read))
{
    //Creates a new Word document.
    using (WordDocument document = new WordDocument(inputStream, FormatType.Docx))
    {
        // Create the bookmark navigator instance
        BookmarksNavigator bookmarkNavigator = new BookmarksNavigator(document);
        // Move to the bookmark
        bookmarkNavigator.MoveToBookmark("Adventure_Bkmk");
        // Get the bookmark content as a new Word document part.
        WordDocumentPart bookmarkPart = bookmarkNavigator.GetContent();
        // Load the extracted content into a temporary Word document for modification or export.
        using (WordDocument tempDoc = bookmarkPart.GetAsWordDocument())
        {
            //Creates file stream.
            using (FileStream outputFileStream = new FileStream(Path.GetFullPath(@"Output/Result.html"), FileMode.Create, FileAccess.ReadWrite))
            {
                //Saves the Word document to file stream.
                tempDoc.Save(outputFileStream, FormatType.Html);
            }
        }             
    }
}
