Question

我必须创建一个以下html结构：

<figure class="op-interactive">
    <iframe>
        <div>
            <script async="" height="" src="src" width=""></script>
        </div>
    </iframe>
</figure>

这是我的代码：

$media_embed = $doc->getElementsByTagName('div');
foreach ($media_embed as $media){
    $scriptstag = $media->getElementsByTagName('script');                           
    foreach ($scriptstag as $scripts) {
        $src= $scripts->getAttribute('src');
        $newFigure = $doc->createElement('figure');
        $newFigure->setAttribute('class','op-interactive');

        $newiFrame = $doc->createElement('iframe');
        $newFigure->appendChild($newiFrame);

        $newDiv = $doc->createElement('div');
        $newiFrame->appendChild($newDiv);                                   

        $scripts->parentNode->insertBefore($newFigure, $scripts);
        $newiFrame->appendChild($scripts);
    }
}
$body1 = $doc->saveHTML($doc->documentElement);

但是输出是这样的：

<figure class="op-interactive">
    <iframe>
        <div>
        </div>
        <script async="" height="" src="src" width=""></script>
    </iframe>
</figure>

我不知道如何在script标签之间插入div标签，我的代码中缺少什么吗？我正在使用此页面分享我的测试：http://sandbox.onlinephpfunctions.com/code/00c285949a467fe44d4a5ce2ed002e6b0ef670a6

能请你帮我吗？谢谢

Answer 1

您要将脚本追加到$newiFrame

尝试将其添加到div中： $newDiv->appendChild($scripts);

Answer 2

我找到了一种方法：

$body1='<div class="media_embed"><script async="" height="" src="src"></script></div>';
$htmlEncoded = mb_convert_encoding($body1, 'HTML-ENTITIES', 'UTF-8');
$doc = new DOMDocument;
$opcionesLibXML = LIBXML_COMPACT | LIBXML_HTML_NODEFDTD;
@$doc->loadHTML($htmlEncoded, $opcionesLibXML);
$media_embed = $doc->getElementsByTagName('div');
foreach ($media_embed as $media){
    $scriptstag = $media->getElementsByTagName('script');
    foreach ($scriptstag as $scripts) {
        $iframe = $doc->createElement('iframe');
        $div = $doc->createElement('div');
        $newScript = $doc->createElement('newscript');
        $newScript->setAttribute('src', $scripts->getAttribute('src'));
        $figure = $doc->createElement('figure');
        $figure->setAttribute('class','op-interactive');
        $figure->appendChild($iframe);
        $iframe->appendChild($div);
        $div->appendChild($newScript);
        $scripts->parentNode->replaceChild($figure, $scripts);

    }
}
$body1 = $doc->saveHTML($doc->documentElement);
$body1 = str_replace('<newscript', '<script', $body1);
$body1 = str_replace('</newscript>', '</script>', $body1);
echo $body1;

但我不知道为什么要使用：

$newScript = $doc->createElement('newscript');

我收到此错误：

Fatal error:  Maximum execution time of 3 seconds exceeded

为什么我使用newscript然后替换那个标签
