防止 PHP DOMDocument 删除 @click 属性

Gij*_*ese 8 php domdocument

我有一个 HTML 代码,其中有一些 JS 库使用的诸如@click、之类的属性。@autocomplete:change

当我使用 DOMDocument 解析 HTML 时,这些属性将被删除。

示例代码:

<?php

$content = <<<'EOT'
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" lang="en">
    <head></head>
    <body>
        <a role="tab" @click="activeType=listingType"></a>
        <input type="text" @autocomplete:change="handleAutocomplete">
    </body>
</html>
EOT;

// creating new document
$doc = new DOMDocument('1.0', 'utf-8');
$doc->recover = true;
$doc->strictErrorChecking = false;

//turning off some errors
libxml_use_internal_errors(true);

// it loads the content without adding enclosing html/body tags and also the doctype declaration
$doc->LoadHTML($content, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);

echo $doc->saveHTML();
?>

如果属性名没办法DOMDocument接受的话,我们可以用特殊的字符串 before替换,after 替换回来@@loadHTML()saveHTML()

<?php

$content = <<<'EOT'
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" lang="en">
    <head></head>
    <body>
        <a role="tab" @click="activeType=listingType"></a>
        <input type="text" @autocomplete:change="handleAutocomplete">
    </body>
</html>
EOT;

// creating new document
$doc = new DOMDocument('1.0', 'utf-8');
$doc->recover = true;
$doc->strictErrorChecking = false;

//turning off some errors
libxml_use_internal_errors(true);

$content = str_replace('@', 'at------', $content);
// it loads the content without adding enclosing html/body tags and also the doctype declaration
$doc->LoadHTML($content, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);

$html = $doc->saveHTML();
$html = str_replace('at------', '@', $html);
echo $html;
