使用SimpleXML删除多个空节点

I want to delete all the empty nodes in my XML document using SimpleXML

Here is my code :

$xs = file_get_contents('liens.xml')or die("Fichier XML non chargé");
$doc_xml = new SimpleXMLElement($xs);
foreach($doc_xml->xpath('//*[not(text())]') as $torm)
    unset($torm);   
$doc_xml->asXML("liens.xml");

I saw with a print_r() that XPath is grabbing something, but nothing is removed from my XML file.

    I know this post is a bit old but in your foreach, $torm is replaced in every iteration. This means your unset($torm) is doing nothing to the original $doc_xml object.

    Instead you will need to remove the element itself:

    foreach($doc_xml->xpath('//*[not(text())]') as $torm)
        unset($torm[0]);
                   ###
    

    by using a simplxmlelement-self-reference.
