In case you would like to do that with xpath (your example is just demanding str_replace however), you can query the &nbsp entity as a string (Demo):

$html = '<body><p>&nbsp;</p>
<p>&nbsp;</p>
<p>&nbsp;</p>
<p>Not empty :)</p>
</body>';

$dom = new DomDocument();
$dom->loadhtml($html);
$xpath = new DomXPath($dom);
$col = $xpath->query("//p[text()=\"\xC2\xA0\"]"); # &nbsp;
foreach($col as $e) {
    $e->parentNode->removeChild($e);
}
echo $dom->saveXML($dom->getElementsByTagName('body')->item(0));

Hope this is helpful if you need to query &nbsp; with xpath.

If you want to remove a string that is exactly, always, '<p>&nbsp;</p>', the simplest and fastest solution is probably to use str_replace() :

$new_string = str_replace('<p>&nbsp;</p>', '', $old_string);

I don't think it's necessary to use DOM for such a simple case -- and a regex is not necessary here.


Of course, if you need to replace something more complex, that is not always exactly the same string... well, it'll be time for DOM manipulations ;-)

preg_replace("|<p>&nbsp;</p>|", "", "<p>&nbsp;</p>
<p>&nbsp;</p>
<p>&nbsp;</p>");
