cod*_*ama 20 html php tags replace domparser
我有以下html:
<html>
<body>
bla bla bla bla
<div id="myDiv">
more text
<div id="anotherDiv">
And even more text
</div>
</div>
bla bla bla
</body>
</html>
我希望从<div id="anotherDiv">关闭之前删除所有内容<div>.我怎么做？

使用原生DOM
$dom = new DOMDocument;
$dom->loadHTML($htmlString);
$xPath = new DOMXPath($dom);
$nodes = $xPath->query('//*[@id="anotherDiv"]');
if($nodes->item(0)) {
$nodes->item(0)->parentNode->removeChild($nodes->item(0));
}
echo $dom->saveHTML();

您可以使用preg_replace():
$string = preg_replace('/<div id="someid"[^>]+\>/i', "", $string);
除了Haim Evgi的回答,使用libxml:
功能
$html='<html>
<body>
bla bla bla bla
<div id="myDiv">
more text
<div id="anotherDiv">
And even more text
</div>
</div>
bla bla bla
</body>
</html>';
编辑
处理 doctype
$dom=new DOMDocument;
$dom->validateOnParse = false;
$dom->loadHTML( $html );
// get the tag
$div = $dom->getElementById('anotherDiv');
// delete the tag
if( $div && $div->nodeType==XML_ELEMENT_NODE ){
$div->parentNode->removeChild( $div );
}
echo $dom->saveHTML();
