How to Identify Bookmark Placement in Word Document in .NET Core?

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 identify bookmark placement in Word document header, footer, or text body using C#.

Overview of the Find Bookmark Placement in Word Document Logic:

• Open the input Word document.
• Iterate through the bookmark collection and retrieve the bookmark start owner paragraph of each bookmark.
• Traverse the paragraph’s owner hierarchy until reaching the Section, stopping if a HeaderFooter is found.
• Determine whether the bookmark resides in the text body, header, or footer.
• Print the bookmark name along with its owner type.

Steps to identify bookmark placement in Word document header, footer, or text body:

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 identify bookmark placement in Word document header, footer, or text body.
   C#

// Load the existing Word document
WordDocument document = new WordDocument(Path.GetFullPath("Data/Template.docx"));
// Iterate through all bookmarks in the document.
foreach (Bookmark bookmark in document.Bookmarks)
{
    // Get bookmark start from the current bookmark
    BookmarkStart bkmkStart = bookmark.BookmarkStart;
    if (bkmkStart != null)
    {
        // Get the paragraphs that contain the bookmark's start.
        Entity ownerEntity = bkmkStart.OwnerParagraph;
        // Traverse the owner hierarchy until reaching the section, stopping if a HeaderFooter is found
        while (!(ownerEntity is WSection))
        {
            if (ownerEntity.EntityType == EntityType.HeaderFooter)
                break;
            ownerEntity = ownerEntity.Owner;
        }
        // Check if the bookmark is in the text body, header, or footer
        string ownerLabel = (ownerEntity.EntityType == EntityType.Section)
            ? "TextBody"
            : CheckHeaderFooterType(ownerEntity.Owner as WSection, ownerEntity as HeaderFooter);
        // Print the bookmark name and its owner type
        Console.WriteLine("Bookmark Name:" + bkmkStart.Name + "\n  Bookmark Owner:" + ownerLabel);                    
    }
}
Console.ReadLine();

5. Use the following code example to check if a bookmark is located in a Header or Footer.
   C#

 private static string CheckHeaderFooterType(WSection section, HeaderFooter headerFooter)
{
    string type = "Header and Footer";
    // Check if the given HeaderFooter instance is one of the section's header references.
    if (section.HeadersFooters.OddHeader == headerFooter
        || section.HeadersFooters.FirstPageHeader == headerFooter || section.HeadersFooters.EvenHeader == headerFooter)
    {
        type = "Header";
    }
    // Otherwise, check if it is one of the section's footer references.
    else if (section.HeadersFooters.OddFooter == headerFooter || section.HeadersFooters.EvenFooter == headerFooter
        || section.HeadersFooters.FirstPageFooter == headerFooter)
    {
        type = "Footer";
    }
    return type;
}
