我正在使用DOM来解析字符串.我需要功能来剥离标签及其内容.例如,如果我有：
This is some text that contains photo. <span class='title'> photobyile</span>
我希望函数返回
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,但我不知道如何获取整个标签,以及类名.
谢谢,
岛
尝试直接从DOM树中删除跨距.

$dom->loadHTML($string);
$dom->preserveWhiteSpace = false;
$elements = $dom->getElementsByTagName('span');
while($span = $elements->item(0)) {
$span->parentNode->removeChild($span);
}
echo $dom->saveHTML();
