You can simple use the below code:

private void btnDelete_Click(object sender, EventArgs e)
{
    var xDoc = XDocument.Load(strFilename);

    foreach (var elem in xDoc.Document.Descendants("product"))
    {
        foreach (var attr in elem.Attributes("name"))
        {
            if (attr.Value.Equals("Tide"))
                elem.RemoveAll();
        }
    }

    xDoc.Save(destinationFilename);
    MessageBox.Show("Deleted Successfully");
}

Happy Coding…
