I have been trying to modify an XML document within an archived .tgz file by using the PharData class using php. I have no problem modifying the XML through DomDocument class, but I am having a hard time saving the whole process: I end up saving 2 different .phar documents alltogether, w/o modifying anything in the .tgz archive :

Here is the code I have been using :

            $phar = new PharData($path . '/' . $idClient . '/' . $tempDate->format('ym') . '/' . $file);



            echo $phar . "\n";



            $dom = new DOMDocument();

            $dom->load ('phar://' . $path . '/' . $idClient . '/' . $tempDate->format('ym') . '/' . $file . '/' . substr($file, 0, -4) . '.xml');



            if ($dom === null) continue;

            $ids = $dom->documentElement->getElementsByTagName('id');



            foreach ($ids as $i_id) {

                if ($i_id->nodeValue !== $id) continue;

                echo $i_id->nodeValue . "\n";

                echo $i_id->nodeName . "\n";

                $sensor = $i_id->parentNode;

                echo $sensor->nodeName . "\n";

                foreach ($sensor->childNodes as $object) {

                    if ($object->nodeName !== 'type') continue;

                    echo $object->nodeName . "\n";

                    echo $object->nodeValue . "\n";

                    $object->nodeValue = $type;

                    echo $object->nodeValue . "\n" . "\n";

                }       

            }

            $dom->save('phar://' . $path . '/' . $idClient . '/' . $tempDate->format('ym') . '/' . $file . '.phar' . '/' . substr($file, 0, -4) . '.xml');

My Answer:
$phar = new PharData($path . '/' . $idClient . '/' . $tempDate . '.tgz');

// Extract the XML file from the archive
$xmlFile = $phar['example.xml']->getContent();

// Modify the XML using DomDocument
$dom = new DomDocument();
$dom->loadXML($xmlFile);
// Make your modifications here

// Save the modified XML back to the archive
$phar->addFromString('example.xml', $dom->saveXML());

// Close the PharData object
unset($phar);

This code should extract the XML file from the .tgz archive, modify it using DomDocument, and then save the modified XML back to the archive. Make sure to replace 'example.xml' with the actual name of the XML file you want to modify.
