Question

我有一张表，我希望在td中获得具有类名ng-binding的href和td值（class =＆＃34; ng-binding＆＃34;）。

我当前的代码正确获取了href值但我想获得相应的td值（ testfolder / 30 section / this-is-a-sample-video.mp4 AND testfolder / 29 section / this- is-a-sample-video2.mp4 ）。例如，我想要以下数据：

1）https://somesite.com/sky/download/123456789/5/this-is-a-sample-video.mp4： testfolder / 30 section / this-is-a-sample-video.mp4

2）https://somesite.com/sky/download/123456789/5/this-is-a-sample-video2.mp4： testfolder / 29 section / this-is-a-sample-video2.mp4

如果专家告诉我如何在td前面以粗体显示href和值，我将不胜感激。提前谢谢。

Answer 1

您当前的$div元素（实际上是<td>）是一个DOMNote，因此您拥有textContent属性，在这里您可以拆分该字符串（\r\n只获得第一行，这就是你要找的东西。）

以下是对您的代码的更新：

foreach ($dom->getElementsByTagName('td') as $div) {
    if($div->getattribute('class') == 'ng-binding') {
        $divContent = $div->textContent;
        $relevantContent = explode("\r\n", $divContent)[0];
        foreach($div->getElementsByTagName('a') as $link) {
            $downloadurl = $link->getattribute('href');
            if ($downloadurl !="javascript:void(0);" & $downloadurl !="") {
                $counter++;
                echo "{$counter}){$downloadurl} :{$relevantContent}<br>\n";        
            }
        }
    }
}

Answer 2

如果您想获取文字内容，可以使用echo $div->textContent;，但会输出

1)https://somesite.com/sky/download/123456789/5/this-is-a-sample-video.mp4
:testfolder/30 section/this-is-a-sample-video.mp4 View Download Upload 2)https://somesite.com/sky/download/123456789/5/this-is-a-sample-video2.mp4
:testfolder/29 section/this-is-a-sample-video2.mp4 View Download Upload

使用View Download Upload，因为这也是td标记内的文字。

Answer 3

要获取所需的文字，您需要使用$div->textContent，但要删除子元素的文字内容，您需要从{{div中移除td个孩子1}} node：

foreach ($dom->getElementsByTagName('td') as $div) {
    if ($div->getattribute('class') == 'ng-binding') {
        foreach ($div->getElementsByTagName('a') as $link) {
            $downloadurl = $link->getattribute('href');
            if ($downloadurl != "javascript:void(0);" && $downloadurl != "") {
                $counter++;
                $subdiv = $div->getElementsByTagName('div')->item(0);
                $div->removeChild($subdiv);
                $td_content = trim($div->textContent);
                echo "$counter)$downloadurl: $td_content<br>";
            }
         }
    }
}

此外，如果您& &&应为griddata，则您的姓氏会输入错误。
