这个问题之前是我的问题:get specific data from php cURL
现在这是我的代码:
$html = file_get_contents('https://nolp.dhl.de/nextt-online-public/de/search?piececode=TRACKING_NUMBER');
$dom = new DOMDocument;
$dom->loadHTML($html);
foreach ($dom->getElementsByTagName('td') as $node) {
echo $dom->saveHtml($node);
}
我的$ html变量的一部分:
<table>
<tr>
<td data-label="Date">xxx</td>
<td data-label="Location">xxx</td>
<td data-label="State">xxx</td>
</tr>
<tr>
<td data-label="Date">xxx</td>
<td data-label="Location">xxx</td>
<td data-label="State">xxx</td>
</tr>
<tr>
<td data-label="Date">xxx</td>
<td data-label="Location">xxx</td>
<td data-label="State">xxx</td>
</tr>
<tr>
<td data-label="Date">xxx</td>
<td data-label="Location">xxx</td>
<td data-label="State">xxx</td>
</tr>
</table>
使用上面的代码,我获得了具有<td>
标记的元素的所有值。
但是,如何获取data-label属性=“Date”的所有<td>
标记的值?
非常感谢:)
答案 0 :(得分:0)
尝试:
$html = '<table>
<tr>
<td data-label="Date">xD1</td>
<td data-label="Location">xxx</td>
<td data-label="State">xxx</td>
</tr>
<tr>
<td data-label="Date">xD2</td>
<td data-label="Location">xxx</td>
<td data-label="State">xxx</td>
</tr>
</table>';
$dom = new DOMDocument;
$dom->loadHTML($html);
foreach ($dom->getElementsByTagName('td') as $node) {
//echo $dom->saveHtml($node);
if ($node->getAttribute('data-label') == "Date")
{
echo $node->nodeValue;
echo "<br>";
}
}
<强>输出:强>
