PHP Dom删除元素留下内容

Question

我试图删除某些链接取决于他们的ID标记,但保留链接的内容.例如,我想转

Some text goes <a href="http://www.domain.tdl/" id="remove">here</a>

至

Some text goes here

我尝试过使用以下内容.

$dom = new DOMDocument;
$dom->loadHtml(mb_convert_encoding($html, 'HTML-ENTITIES', "UTF-8"));
$xp = new DOMXPath($dom);

foreach($xp->query('//a[contains(@id="remove")]') as $oldNode) {
$revised = strip_tags($oldNode);
}

$revised = mb_substr($dom->saveXML($xp->query('//body')->item(0)), 6, -7, "UTF-8");
echo $revised;

大致从这里开始,但它只是吐出相同的内容$html.

有什么想法我会如何实现这一目标？

Answer 1

这是我的功能:

function DOMRemove(DOMNode $from) {
    $sibling = $from->firstChild;
    do {
        $next = $sibling->nextSibling;
        $from->parentNode->insertBefore($sibling, $from);
    } while ($sibling = $next);
    $from->parentNode->removeChild($from);    
}

所以这:

$dom->loadHTML('Hello <a href="foo"><span>World</span></a>');
$a = $dom->getElementsByTagName('a')->item(0); // get first
DOMRemove($a);

应该给你:

Hello <span>World</span>

要获取具有特定ID的节点,请使用XPath:

$xpath = new DOMXpath($dom);
$node = $xpath->query('//a[@id="something"]')->item(0); // get first
DOMRemove($node);
