在我的案例页面中，多个table具有相同的类，因此我在tr,td and plaintext的帮助下找到了价值。

PHP部分：

$html = file_get_html('http://www.example.com/');
$eles = $html->find('.info-tab');
foreach($eles as $e) {
    if(strpos($e->find('tr',0)->plaintext,"Information about the manufacturer and the model." ) ) {
    $value1 = $e->find('td',1)->plaintext;
    }

    if(strpos($e->find('tr',1)->plaintext,"Information about the manufacturer and the model." ) ) {
    $value2 = $e->find('td',1)->plaintext;
    }
}
echo $value1;
echo $value2;

// Here's will be many other "Table" with diffrent text but class & ID are same...

<table class="info-tab">
    <tbody>
        <tr>
            <td>Information about the manufacturer and the model.</td>
            <td>1000</td>
        </tr>
        <tr>
            <td>dummy text</td>
            <td>dummy text</td>
        </tr>
    </tbody>
</table>

<table class="info-tab">
    <tbody>
        <tr>
            <td>dummy text</td>
            <td>dummy text</td>
        </tr>
        <tr>
            <td>Information about the manufacturer and the model.</td>
            <td>3000</td>
        </tr>
        <tr>
            <td>dummy text</td>
            <td>dummy text</td>
        </tr>
    </tbody>
</table>

页面有多个表20加号，只有两个表具有此文本，所以我想复制它们。

如何找到这两个值？
