How to select the second tr of my HTML?

Question

The code below works but it only selects the first tr:

My HTML:

<script>if(''!='') { document.Form2.endereco_ip.value='';}</script> 
<div style="font-size: 10pt; font-weight: bold">Listagem
</div>
<hr style="height: 1px">
<table width="100%" cellpadding="2" cellspacing="1" border="1" style="border-collapse: collapse">
  <tbody>
    <tr style="background-color: #E8E8E8">
      <td width="1%">&nbsp;
      </td>
      <td width="5%">
        <b>Rede
        </b>
      </td>
      <td width="5%">
        <b>Tipo
        </b>
      </td>
      <td width="5%">
        <b>Portal
        </b>
      </td>
      <td width="20%">
        <b>Nome do Portal
        </b>
      </td>
      <td width="10%">
        <b>Franqueador
        </b>
      </td>
      <td width="10%">
        <b>Ambiente
        </b>
      </td>
      <td width="10%">
        <b>Endereço BD
        </b>
      </td>
      <td width="15%">
        <b>Endereço Páginas
        </b>
      </td>
      <td width="5%">
        <b>Release
        </b>
      </td>
      <td width="5%">
        <strong>Administrador</strong>
      </td>
    </tr>
    <tr>
      <td bgcolor="green" title="xxx">
      </td>
      <td>Nome_emp
      </td>
      <td>Cliente
      </td>                 
      <td>
        <a target="_blank" title="Descricao." href="#">1149</a>                                                     
      <td>Nome_emp 
        <b> - Empresa: 19; 
        </b>
      </td>
      <td>9841 - Nome - empresa
      </td>
      <td>Micro (95%)
      </td>
      <td>LINK.COM.BR
      </td>
      <td>
        <a href="http://#" target="_blank"><font color="blue">http://#
          </font></a>
      </td>
      <td>2.0
      </td>
      <td class="style1">
      </td>
    </tr>
  </tbody>
</table>

My Selenium code:

driver.Navigate().GoToUrl("http://...");
IWebElement secondRow = driver.FindElement(By.CssSelector("table tr:nth-of-type(2)"));
portalweb = driver.FindElement(By.CssSelector("td:nth-of-type(4)")).Text;
txbPortal.Text = portalweb;

Answer 1

To add explanation to what you have already figured out. The problem was that with this line you correctly acquired the second row:

IWebElement secondRow = driver.FindElement(By.CssSelector("table tr:nth-of-type(2)"));

but with the next piece of code, you did not get the 4th cell of the second row, but the first 4th cell of the DOM and that starts from the first row, the header. That is why it has returned "portal".

portalweb = driver.FindElement(By.CssSelector("td:nth-of-type(4)")).Text;

so instead of the previous line you should do what you have already figured out:

portalweb = secondRow.FindElement(By.CssSelector("td:nth-of-type(4)")).Text;

run the second FindElement on the second row, and not on the whole DOM again.

Answer 2

I made the following change and it worked:

portalweb = secondRow.FindElement(By.CssSelector("td:nth-of-type(4)")).Text;
