正在删除 PHP 中的 HTML 属性

Question

我有这样的 HTML 代码：

<figure id="attachment_83" aria-describedby="caption-attachment-83" style="width: 300px" class="wp-caption alignnone">
    <img class="size-medium wp-image-83" src="https://sampleonly.com/wp-content/uploads/2020/01/my-picture-300x169.jpg"
        alt="" width="300" height="169"
        srcset="https://sampleonly.com/wp-content/uploads/2020/01/my-picture-300x169.jpg 300w, https://sampleonly.com/wp-content/uploads/2020/01/my-picture-1024x576.jpg 1024w, https://sampleonly.com/wp-content/uploads/2020/01/my-picture-768x432.jpg 768w, https://sampleonly.com/wp-content/uploads/2020/01/my-picture-1536x864.jpg 1536w, https://sampleonly.com/wp-content/uploads/2020/01/my-picture-1218x685.jpg 1218w, https://sampleonly.com/wp-content/uploads/2020/01/my-picture.jpg 1920w"
        sizes="(max-width: 300px) 100vw, 300px" />
    <figcaption id="caption-attachment-83" class="wp-caption-text">This is my picture text.</figcaption>
<figure>

我想删除 id, style, class 等等最后的代码是这样的：

<figure>
    <img src="https://sampleonly.com/wp-content/uploads/2020/01/my-picture.jpg"/>
    <figcaption>This is my picture text.</figcaption>
<figure>

这里有人可以帮助我吗？先谢谢了

Answer 1

这是 preg 替换，您可以使用它来删除所需属性以外的属性。

$html = preg_replace("/(<img\s)[^>]*(src=\S+)[^>]*(\/?>)/i", "", $html);
$html = preg_replace("/(<figure\s)[^>]*[^>]*(\/?>)/i", "", $html);
$html = preg_replace("/(<figcaption\s)[^>]*[^>]*(\/?>)/i", "", $html);

这将为您提供输出

<figure ><img src="https://sampleonly.com/wp-content/uploads/2020/01/my-picture-300x169.jpg"><figcaption >This is my picture text.</figcaption><figure>

Answer 2

您可以使用下面的代码注意：如果您包含 jquery 则仅使用脚本，否则使用下面的 jquery link

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>

    <script>
        $('figure,figcaption,img').removeAttr("id style class height width sizes   srcset aria-describedby");
    </script>
