i have using HtmlAgilityPack parse data on webbrowser, Now I want to use xpath to get the data they must do how

code HtmlAgilityPack:

        var document = webBrowser1.Document;
        var documentAsIHtmlDocument3 = (mshtml.IHTMLDocument3)document.DomDocument;

        var htmlString = documentAsIHtmlDocument3.documentElement.innerHTML;

        HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
        doc.LoadHtml(htmlString);


        HtmlNodeCollection texts = doc.DocumentNode.SelectNodes("//div[@class='box-content']//div[@id='ctl00_panelContent_ctl01_ucThuyVan_grdGiaTriNuoc_GridData']");
        string kq = "";

        if (texts != null)
        {
            foreach (var item in texts)
            {
                kq += item.InnerText + Environment.NewLine;
            }
        }
        richTextBox1.Text = kq;

    }
}
