Solution:

the first problem is variable name preg_match($searchpattern, $valuesPICtnN, $valuesPICt); and correct is $valuesPICtn

Even so, it doesn't solve the final problem!!!!

As you have already converted the XML from string to object.

Just use the code below that I tested and it works.

$content = '<?xml version="1.0" encoding="utf-8"?><OBJEKT ID="91727"><PICTURE ID="7"><ID>7</ID><PIC>&lt;IMG SRC="https://d1.cloudfront.net/00722.jpg" width="640" height="480" BORDER=0></PIC></PICTURE><PICTURE ID="11"><ID>11</ID><PIC>&lt;IMG SRC="https://d1.cloudfront.net/01123.jpg" width="640" height="480" BORDER=0></PIC></PICTURE><PICTURE ID="2"><ID>2</ID><PIC>&lt;IMG SRC="https://d1.cloudfront.net/00224.jpg" width="640" height="480" BORDER=0></PIC></PICTURE><PICTURE ID="9"><ID>9</ID><PIC>&lt;IMG SRC="https://d1.cloudfront.net/00925.jpg" width="640" height="480" BORDER=0></PIC></PICTURE></OBJEKT>';
$xml = simplexml_load_string($content);
$valuesPICtn = $xml->xpath("//OBJEKT//PICTURE");
$display = '';
foreach ($valuesPICtn as $PICelements) {
    $display .= '<li>';
    $display .= ''.$PICelements->PIC.'';
    $display .= '</li>';
}
echo "<ul>";
echo $display;
echo "</ul>";

You just need to filter all as occurrences with this $valuesPICtn = $xml->xpath("/OBJEKT//PICTURE");

and then then

foreach ($valuesPICtn the $PICelements) {
...
