                    <tr>
                        <td class="style_19" style="vertical-align: baseline;">
                            <div class="style_18">AA00857</div>
                        </td>
                        <td class="style_19" style="vertical-align: baseline;">
                            <div></div>
                            <div class="style_20">TPRCF</div>
                        </td>
                        <td class="style_19" style="vertical-align: baseline;">
                            <div class="style_21"></div>
                        </td>

                        </td>
                        <td class="style_19" style="vertical-align: baseline;">

i need to extract from the above these values:

AA00857, TPRCF, 16908/2, ETG_C

so far all i have is this:

HtmlWeb hw = new HtmlWeb();
            HtmlAgilityPack.HtmlDocument htmlDoc = hw.Load(@"http://www.some123123site.com/index");



            if (htmlDoc.DocumentNode != null)
            {
                HtmlAgilityPack.HtmlNode bodyNode = htmlDoc.DocumentNode.SelectSingleNode("//tbody");

                if (bodyNode != null)
                {
                    // Do something with bodyNode
                }
            }

please help!

Try this:

HtmlWeb hw = new HtmlWeb();              
HtmlAgilityPack.HtmlDocument htmlDoc = hw.Load(@"http://www.some123123site.com/index");                 
if (htmlDoc.DocumentNode != null)              
{                   
        foreach(HtmlNode text in htmlDoc.DocumentNode.SelectNodes("//tr/td/div/text()"))
        {     
            Console.WriteLine(text.InnerText);  
        }
}
