Question

I have this post earlier regarding removing the html tags that have empty text node.

$dom = new DOMDocument();
$dom->loadHtml(
    '<p><strong><a href="http://xx.org.uk/dartmoor-arts">test</a></strong></p>
    <p><strong><a href="http://xx.org.uk/depw"></a></strong></p>
    <p><strong><a href="http://xx.org.uk/devon-guild-of-craftsmen"></a></strong></p>
    <p>this line has a <br/>break</p>
    '
);

$xpath = new DOMXPath($dom);


while(($nodeList = $xpath->query('//*[not(text()) and not(node())]')) && $nodeList->length > 0) {
    foreach ($nodeList as $node) {
        $node->parentNode->removeChild($node);
    }
}


echo $dom->saveHtml();

it works perfectly but I don’t want it to remove <br/> tag – how can I keep it?

Answer 1

Use this XPath (it excludes br nodes):

//*[not(text() or node() or self::br)]
