Here is the sample html:

$html = '<table>

                <tbody>

                    <tr>

                        <td><span style="background-color: #f1c40f;">Cell 1</span></td>

                        <td>Cell 2</td>

                    </tr>

                </tbody>

            </table>';

            

Target is to retrieve everything between "td" tags, including the "span" tag, if any. Here is the expected result:

<span style="background-color: #f1c40f;">Cell 1</span>

Cell 2

I tried to use DOMDocument()->getElementsByTagName("td")->saveHTML() and nodeValue without success.

Here is the php code I tried:

$html = '<table>

                <tbody>

                    <tr>

                        <td><span style="background-color: #f1c40f;">Cell 1</span></td>

                        <td>Cell 2</td>

                    </tr>

                </tbody>

            </table>';

            $doc = new DOMDocument();

    $doc->loadHTML('<?xml encoding="utf-8" ?>' . $html);

    $tds = $doc->getElementsByTagName("td");

    foreach($tds as $td){

        dump('saveHTML: '.$doc->saveHTML($td));

        dump('nodeValue: '.$td->nodeValue);

    }

    die();

Here is the outputs:

^ "saveHTML: <td><span style="background-color: #f1c40f;">Cell 1</span></td>"

^ "nodeValue: Cell 1"

^ "saveHTML: <td>Cell 2</td>"

^ "nodeValue: Cell 2"

Did I do anything wrong? Thanks a lot!

My Answer:
';
// Load the HTML string
$dom = new DOMDocument();
$dom->loadHTML($html);
// Get the

element
$p = $dom->getElementsByTagName('p')->item(0);
// Get the node value of the

element
$nodeValue = '';
foreach ($p->childNodes as $node) {
$nodeValue .= $dom->saveHTML($node);
}
echo $nodeValue; // Output: This is a sample paragraph.
