How to save HTML with indentation of attributes?

本文关键字：保存 HTML 缩进属性何用 | 更新日期: 2023-09-27

我有这个结果(使用$dom->saveHTML()):

<!DOCTYPE html>
<html>
    <head>
        <title>Complete!</title>
    </head>
    <body>
        <div id="foo" class="bar baz" data-foo="a" data-bar="b" data-baz="c"></div>
    </body>
</html>

但是我想用缩进的属性保存结果:

<!DOCTYPE html>
<html>
    <head>
        <title>Complete!</title>
    </head>
    <body>
        <div id="foo"
                class="bar baz"
                data-foo="a"
                data-bar="b"
                data-baz="c"></div>
    </body>
</html>

如何使它与本地(?)php DOMDocument/DOMNode/DOMElement/别的东西?

乌利希期刊指南:是的!我真的需要那种特定的格式来让人读懂。

他自己回答。也许这将是一个很好的解决方案:

$html = $dom->saveHTML();
$html = html_entity_decode($html, ENT_QUOTES, 'UTF-8');
$html = explode("'n", $html);
foreach ($html as $num => $line) {
    if (preg_match('/^('s*<[a-z]+'s+)([^>]+)(>)(.*)$/s', $line, $m)) {
        $offset = ceil(mb_strlen($m[1]) / 4);
        $attrs  = preg_split('/"'s+/', $m[2]);
        $attrs  = join("'"'n" . str_repeat('    ', $offset), $attrs);
        $html[$num] = $m[1] . $attrs . $m[3] . $m[4];
    }
}
$html = join("'n", $html);
