如何使用简单的html dom获得具有相同类和明文的td值

Question

我想在BASIC EPS下找到td值，但是有两个这样的列，因此很难选择我想要的第二列（从值> 0.82> 1.05> .74等开始） 。我在一个带有简单html dom库的php脚本中这样做，所以让我知道它是如何实现的。我使用的代码如下。但是上面的代码给了我两次基本的eps值，而我在第二列只需要一次。

<tr height="22px">
    <td colspan="2" class="detb" width="40%">EPS Before Extra Ordinary</td>

    <td align="right" class="detb"></td>
    <td align="right" class="detb"></td>
    <td align="right" class="detb"></td>
    <td align="right" class="detb"></td>
</tr>


<tr height="22px">
    <td colspan="1" class="det" width="40%">Basic EPS</td>

    <td align="right" class="det">0.82</td>
    <td align="right" class="det">1.05</td>
    <td align="right" class="det">0.74</td>
    <td align="right" class="det">1.00</td>
    <td align="right" class="det">0.96</td>
</tr>


<tr height="22px">
    <td colspan="1" class="det" width="40%">Diluted EPS</td>

    <td align="right" class="det">0.82</td>
    <td align="right" class="det">1.05</td>
    <td align="right" class="det">0.74</td>
    <td align="right" class="det">1.00</td>
    <td align="right" class="det">0.96</td>
</tr>


<tr height="22px">
    <td colspan="2" class="detb" width="40%">EPS After Extra Ordinary</td>

    <td align="right" class="detb"></td>
    <td align="right" class="detb"></td>
    <td align="right" class="detb"></td>
    <td align="right" class="detb"></td>
</tr>


<tr height="22px">

    <td align="right" class="det">0.74</td>
    <td align="right" class="det">1.00</td>
    <td align="right" class="det">0.96</td>

$mn=$html->find("td.det");

            $qeps10 = $next_td->plaintext; 
            echo $qeps10."<br>"; 
            $next_td_1=$next_td->next_sibling(); 
            $qeps9 = $next_td_1->plaintext; 
            echo $qeps9."<br>";

        }
    }
