Replace an element using phpquery (php version of jquery)

Question

I want to replace tags <span>with <p>using phpquery. What is wrong with my code? It finds span, but the replaceWith function does nothing.

$event = phpQuery::newDocumentHTML(file_get_contents('event.html'));
$formatted_event = $event->find('span')->replaceWith('<p>');

This documentation states that this is possible:
http://code.google.com/p/phpquery/wiki/Manipulation#Replacing
http://api.jquery.com/replaceWith/

This is the html that returns with and without ->replaceWith('<p></p>')in the code:

<span class="Subhead1">Event 1<br></span><span class="Subhead2">Event 2<br>
    August 12, 2010<br>
    2:35pm <br>
    Free</span>

Answer 1

DOMDocument (DOMDocument phpQuery HTML), - . , , :

$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;
}
