Merge and "<<Next Record>>-" showing for emty records - want to remove them

I am a programmer working with VS C# and some code I inherited to create mailing and folder labels from data in a SQL Server database using Mail Merge. Another person created the MS Word documents that we are using.
Everything works fine, but when there are fewer data records than labels on a sheet, we get “<>.” printed at the top of each label instead of everything just being blank.
We need to find a way to prevent this from happening.
Here is the code from a module:

protected void Page_Load(object sender, EventArgs e)
    // Define the Aspose.Words license
    Aspose.Words.License license = new Aspose.Words.License();
    // Clear the Gridview data source
    gvAdmitLetter.DataSource = null;
protected void btnCreateLetter_Click(object sender, EventArgs e)
    // Open the file chosen by the user
    System.IO.Stream ioStream = File1.PostedFile.InputStream;
    int fileLength = File1.PostedFile.ContentLength;
    byte[] buffer = new byte[fileLength];
    ioStream.Read(buffer, 0, fileLength);
    MemoryStream stream = new MemoryStream(buffer);
    Document doc = new Document(stream);
    string MyPath = HttpContext.Current.Server.MapPath(".");
    // Create a DataView via the data source using Program and Term
    DataView dv = (DataView)dsrcAdmitLetter.Select(DataSourceSelectArguments.Empty);
        // Do the mail merge from the DataVeiew to the document
        // Strip out merged fields with no data
        int i;
        string[] names = doc.MailMerge.GetFieldNames();
        DocumentBuilder builder = new DocumentBuilder(doc);
        for (i = 1; i < names.Length; i++)
        // Save the mail merge document as Out.doc
        doc.Save(MyPath + @"\Out.doc");
        HttpContext.Current.Response.ContentType = "application/ms-word";
        HttpContext.Current.Response.AddHeader("Content-Disposition", "inline;filename=Out.doc");
    catch (Exception ex)
        lblErrors.Text = ex.Message;
    dv = null;
    doc = null;
    stream = null;
    ioStream = null;

Thank you for your interest in Aspose.Words. Could you please attach your template for testing? (only you and Aspose staff can download it). I will investigate this and provide you more information.
Best regards.

Thank you. Please see the attached template file.

Thank you for additional information. NEXT field isn’t MERGEFIELD. You can try using the following code to solve your problem.

Document doc = new Document(@"277_106302_wpatterson\in.doc");
ArrayList list = new ArrayList();
NodeCollection collection = doc.GetChildNodes(NodeType.FieldStart, true);
foreach (FieldStart start in collection)
    if (start.FieldType == FieldType.FieldNext || start.FieldType == FieldType.FieldMergeField)
foreach (Node start in list)
    Node node = start;
    while (node.NodeType != NodeType.FieldEnd)
        node = node.NextSibling;

I hope that this will solve your problem.
Best regards.

Thanks so much! That solved our problem!
