剥离HTML标记及其内容

Question

我正在使用DOM来解析字符串.我需要删除span标签及其内容的功能.例如,如果我有:

This is some text that contains photo.
<span class='title'> photobyile</span>

我想功能返回

This is some text that contains photo.

这是我试过的:

    $dom = new domDocument;
    $dom->loadHTML($string);
    $dom->preserveWhiteSpace = false;
    $spans = $dom->getElementsByTagName('span');

    foreach($spans as $span)
    {
        $naslov = $span->nodeValue; 
        echo $naslov;

        $string = preg_replace("/$naslov/", " ", $string);
    }

我知道$span->nodeValue返回span标签的值而不是整个标签,但我不知道如何获得整个标签以及类名.

谢谢,Ile

尝试直接从DOM树中删除跨度.

$dom = new DOMDocument();
$dom->loadHTML($string);
$dom->preserveWhiteSpace = false;

$elements = $dom->getElementsByTagName('span');
while($span = $elements->item(0)) {       
   $span->parentNode->removeChild($span);
}

echo $dom->saveHTML();
