php - 如何使用 domcrawler 替换特定元素的文本

Question

我已经能够使用 Symfon dom-crawler 库来检索值并更改元素的属性和值，如下面的代码所示。

$doc = new DOMDocument;
$doc->loadHtml(file_get_contents($_SERVER['DOCUMENT_ROOT'].'/pages/example.html'));

// closure => setter function
$crawler = new Crawler($doc);
$setText = function (object $templateData) use ($logger, $crawler, $doc) {
    $crawler->filter($templateData->selector)
        ->each(function (Crawler $crawler) use ($logger, $templateData, $doc) {
            foreach ($crawler as $node) {
                
                //set attributes (classes)..
                if($templateData->setClass){
                    /** @noinspection PhpPossiblePolymorphicInvocationInspection */
                    $node->setAttribute('class', $node->getAttribute('class'). ' '.$templateData->setClass);
                }
                
                //note: this just keeps adding new values
                // to the node but I need a way to replace the
                // text at once instead of just adding new values
                
                //sets values (text only)
                if($templateData->value){
                    //$node->parentNode->insertBefore($doc->createTextNode($value), $node);
                    $node->appendChild($doc->createTextNode($templateData->value));
                }
            }
        });
    
    return $templateData->result?$crawler->html():'result option not enabled!!';
};

有没有办法使用 symfony 的 dom-crawler 仅更改或替换元素的文本..？

任何帮助将不胜感激。谢谢你。
