将可点击的锚标签转换为 html 文档中的纯文本

2021-12-25 00:00:00 replace php domdocument html anchor

我试图在我的内容中匹配 <a> 标签，并将它们替换为链接文本，后跟方括号中的 url 用于打印版本.

I am trying to match <a> tags within my content and replace them with the link text followed by the url in square brackets for a print-version.

如果只有href"，则以下示例有效.如果 <a> 包含另一个属性，则匹配太多并且不会返回所需的结果.

The following example works if there is only the "href". If the <a> contains another attribute, it matches too much and doesn't return the desired result.

如何匹配 URL 和链接文本，仅此而已?

How can I match the URL and the link text and that's it?

这是我的代码:

<?php
$content = '<a href="http://www.website.com">This is a text link</a>';
$result = preg_replace('/<a href="(http://[A-Za-z0-9\.:/]{1,})">([\s\S]*?)</a>/',
     '<strong>\2</strong> [\1]', $content);
echo $result;
?>

想要的结果:

<strong>This is a text link </strong> [http://www.website.com]

推荐答案

您可以使用 ? 使匹配变得不贪婪.您还应该考虑到 href 属性之前可能有一些属性.

You can make the match ungreedy using ?. You should also take into account there may be attributes before the href attribute.

$result = preg_replace('/<a [^>]*?href="(http://[A-Za-z0-9\.:/]+?)">([\s\S]*?)</a>/',
    '<strong>\2</strong> [\1]', $content);
