Remove <p><strong><br /> &nbsp;</strong></p> with XPATH

Question

I use xpath to remove <p>&nbsp;</p>

    $nodeList = $xpath->query("//p[text()=\"\xC2\xA0\"]"); #  
    foreach($nodeList as $node) 
    {
        $node->parentNode->removeChild($node);
    }

but it does not remove this,

<p><strong><br /> &nbsp;</strong></p>

or this kind,

<p><strong>&nbsp;</strong></p>

How can I remove them?

Or maybe a regex that I should use?

Answer 1

Try with

$nodeList = $xpath->query("//p[normalize-space(.)=\"\xC2\xA0\"]"); #  
foreach($nodeList as $node) 
{
    $node->parentNode->removeChild($node);
}

Quoting from the docs

The normalize-space function returns the argument string with whitespace normalized by stripping leading and trailing whitespace and replacing sequences of whitespace characters by a single space.
