How to delete HTML text between html tags in PHP using SimpleHtmlDom

Using http://simplehtmldom.sourceforge.net/ I know this could extract the html text:

<?php
include('simple_html_dom.php');
// Create DOM from URL
echo file_get_html('http://www.google.com/')->plaintext; 

?>

But how to delete all the text?

For example, if I have this input HTML:

<html>
    <head>
        <title>Example</title>
    </head>
    <body>
        <h1>Lore Ipsum</h1>
        <p>
            Lorem ipsum dolor sit amet, consectetuer adipiscing elit.<br/>
            Aenean <em>commodo</em> ligula eget dolor. Aenean massa.
        </p>
    </body>
</html>

I would like to get this output with SimpleHtmlDom:

<html>
    <head>
        <title></title>
    </head>
    <body>
        <h1></h1>
        <p><br/></p>
    </body>
</html>

In other words, I want to keep the structure of the document only.

Please help.

I don't know for sure how to do that with SimpleHtmlDom. From it's manual, I'd assume something like

$html = file_get_html('http://www.google.com/');
foreach( $html->find('text') as $text) {
    $text->plaintext = '';
}

However, you can also use PHP's native DOM parser. It can do XPath queries and should in general be a good deal faster:

libxml_use_internal_errors(TRUE);
$dom = new DOMDocument;
$dom->loadHTMLFile('http://www.google.com');
$xp = new DOMXPath($dom);
foreach ($xp->query('//text()') as $textNode) {
    $textNode->parentNode->removeChild($textNode);
}
$dom->formatOutput = TRUE;
echo $dom->saveXML($dom->documentElement);
