DOMXPath - 如何將元素包裝在 HTML 標簽中？

Question

我想在<p style="text-align:center"></p>扭曲<img>元素。 這是我到目前為止的代碼：

$dom_err = libxml_use_internal_errors(true);
$dom = new \DOMDocument('1.0', 'utf-8');
$dom->loadHtml(mb_convert_encoding($arr['nm_corpo_artigo'], 'HTML-ENTITIES', 'UTF-8'));
$xpath = new \DOMXPath($dom);
foreach ($xpath->query("//figure/img") as $img) {
    $img->setAttribute('style','max-width: 100%; height: auto;');
    $img->setAttribute('class','mb-4 mt-4');
}
$body = $dom->saveHTML();

這是代碼生成的結構：

最后我希望有：

<figure ...>
   <p style="text-align:center"><img ...><figcaption>...</p>
</figure ...>

...

您需要做的是創建一個新的段落元素（具有新屬性）並用這個新標簽替換圖像標簽，然后將 img 標簽添加回新的段落標簽...

foreach ($xpath->query("//figure/img") as $img) {
    $img->setAttribute('style','max-width: 100%; height: auto;');
    $img->setAttribute('class','mb-4 mt-4');
    $p = $dom->createElement("p");
    $p->setAttribute('style', 'text-align:center');
    $img->parentNode->replaceChild($p, $img);
    $p->appendChild($img);
}
