如果您不介意一个普通的 DOMDocument 解决方案(DOMDocument 在 phpQuery 的引擎盖下用于解析 HTML 片段),我不久前做了类似的事情。我修改了代码来做你需要的:
$document = new DOMDocument();
// load html from file
$document->loadHTMLFile('event.html');
// find all span elements in document
$spanElements = $document->getElementsByTagname('span');
$spanElementsToReplace = array();
// use temp array to store span elements
// as you cant iterate a NodeList and replace the nodes
foreach($spanElements as $spanElement) {
$spanElementsToReplace[] = $spanElement;
}
// create a p element, append the children of the span to the p element,
// replace span element with p element
foreach($spanElementsToReplace as $spanElement) {
$p = $document->createElement('p');
foreach($spanElement->childNodes as $child) {
$p->appendChild($child->cloneNode(true));
}
$spanElement->parentNode->replaceChild($p, $spanElement);
}
// print innerHTML of body element
print DOMinnerHTML($document->getElementsByTagName('body')->item(0));
// --------------------------------
// Utility function to get innerHTML of an element
// -> "stolen" from: http://www.php.net/manual/de/book.dom.php#89718
function DOMinnerHTML($element) {
$innerHTML = "";
$children = $element->childNodes;
foreach ($children as $child)
{
$tmp_dom = new DOMDocument();
$tmp_dom->appendChild($tmp_dom->importNode($child, true));
$innerHTML.=trim($tmp_dom->saveHTML());
}
return $innerHTML;
}
也许这可以让你在如何在 phpQuery 中进行替换的正确方向?
编辑:
我给了 replaceWith 的 jQuery 文档,在我看来,你必须传递整个 html 片段,你想将它作为新的替换内容。
这段代码对我有用:
$event = phpQuery::newDocumentHTML(...);
// iterate over the spans
foreach($event->find('span') as $span) {
// make $span a phpQuery object, otherwise its just a DOMElement object
$span = pq($span);
// fetch the innerHTMLL of the span, and replace the span with <p>
$span->replaceWith('<p>' . $span->html() . '</p>');
}
print (string) $event;
我找不到任何方法可以通过一行中的链接方法调用来做到这一点。
