abcdefghijklmn
opqrstuvwxyz
代码如下:
$html =
Test
abcdefghijklmn
opqrstuvwxyz
EOF;
// create document object model
$dom = new DOMDocument();
// load html into document object model
@$dom->loadHTML($html);
// create domxpath instance
$xPath = new DOMXPath($dom);
// get all elements with a particular id and then loop through and print the href attribute
$elements = $xPath->query('//*[@id="content"]/p/span');
$content = $elements->item(0)->nodeValue;
echo $content;

会被去除,使用什么操作比如有没有$e->innerHtml之类的,可以保留html标签。

$content = $dom->saveXml($elements->item(0));
