Php 取消图像链接，删除未关闭的p并删除所有样式

我的Wordpress帖子有一些问题，我正在尝试使用DOMDocument来修复它们

第一个问题是，我的图像位于标记内，我想删除标记

我还想删除所有未关闭的标记，这些标记没有

，我想从所有元素中删除样式

我可以发布一些我尝试过的代码，但我认为这一点都没有帮助，因为我没有用它。目前我只尝试从图片中删除链接，但似乎没有任何效果。我真的不太明白如何很好地使用DOMDocument子元素

这里您可以看到一个需要修复的HTML示例：

稍后编辑：

这是我尝试的，它似乎取消了图像链接，但只有图像编号1,3,5,7，而2,4,6保持不变

谢谢

能否尝试运行此代码，看看您是否满意。这发现我已经设法用DOMDocument和HTML净化器做到了这一点

代码如下：

$p = "/<a\s[^>]*href=(\"??)([^\" >]*?)\\1[^>]*>(.*<img.*)<\/a>/siU";
$newHtml = preg_replace($p, '$3', $html , PREG_SET_ORDER );

如果您的html被破坏，那么请使用htmlpurifier尝试清理它。PHP的dom非常挑剔，充其量只能吐出/吐出所有html，或者更糟。垃圾进来，垃圾出去，我不知道，谢谢。对于未关闭的标签，我将尝试使用它。但是我仍然需要取消图像的链接，我不想用正则表达式来表示HTML。

$p = "/<a\s[^>]*href=(\"??)([^\" >]*?)\\1[^>]*>(.*<img.*)<\/a>/siU";
$newHtml = preg_replace($p, '$3', $html , PREG_SET_ORDER );

require_once 'library/HTMLPurifier.auto.php';
$config = HTMLPurifier_Config::createDefault();
$config->set('HTML.TidyLevel','heavy');
$config->set('AutoFormat.RemoveEmpty','true');
$config->set('AutoFormat.RemoveEmpty.RemoveNbsp','true');
$purifier = new HTMLPurifier($config);

$clean_html = $purifier->purify($content);
$html = new DOMDocument;
$html->preserveWhiteSpace = false;
$html->loadHTML('<meta http-equiv="content-type" content="text/html; charset=utf-8">'.$clean_html);
$as = $html->getElementsByTagName('a');
$ctr = $html->getElementsByTagName('a')->length;
for($i=$ctr;$i>0;--$i) {
    $a = $html->getElementsByTagName('a')->item($i-1);
    if($a->hasChildNodes()) {
        $img = $a->getElementsByTagName('img')->item(0);
        if($img != null) {
            $a->parentNode->replaceChild($img,$a);
        }
    }
}

foreach($html->getElementsByTagName('p') as $p) {
    $p->removeAttribute('style');
}
$text = $html->saveHTML();
echo $text;
