I have an XML like below

    <title lang="en">Sample</title>
    <title lang="fr">Sample</title>

Is there a way in PHP to delete the parent node (entry) based on the title lang attribute? I need to keep only the en ones, so in this case I would need to get the XML without the second entry node.

I tried looking around but couldn't find any solution...

    You need to use DOMDocument class to parse string to XML document. Then use DOMXpath class to find target element in document and use DOMNode::removeChild() to remove selected element from document.

    $doc = new DOMDocument(); 
    $xpath = new DOMXpath($doc);
    // select target entry tag
    $entry = $xpath->query("//entry[title[@lang='fr']]")->item(0);
    // remove selected element
    $xml = $doc->savexml();

    You can check result in demo
