如何使用php从标签(例如段落标签)中剥离所有/任何属性?

How can I use php to strip all/any attributes from a tag, say a paragraph tag?

<p class="one" otherrandomattribute="two">至<p>

答

尽管有更好的方法，但实际上您可以使用正则表达式从html标记中剥离参数:

Although there are better ways, you could actually strip arguments from html tags with a regular expression:

<?php
function stripArgumentFromTags( $htmlString ) {
    $regEx = '/([^<]*<\s*[a-z](?:[0-9]|[a-z]{0,9}))(?:(?:\s*[a-z\-]{2,14}\s*=\s*(?:"[^"]*"|\'[^\']*\'))*)(\s*\/?>[^<]*)/i'; // match any start tag

    $chunks = preg_split($regEx, $htmlString, -1,  PREG_SPLIT_DELIM_CAPTURE);
    $chunkCount = count($chunks);

    $strippedString = '';
    for ($n = 1; $n < $chunkCount; $n++) {
        $strippedString .= $chunks[$n];
    }

    return $strippedString;
}
?>

上面的文字可能用较少的字符书写，但确实可以完成工作(快速又脏).

The above could probably be written in less characters, but it does the job (quick and dirty).
