<?
$string_data = "https://maps.googleapis.com/maps/api/geocode/xml?latlng=41.51,15.16&key=AIzaSyClG_vc2nkQCzXqvDzW1maPrUWLyADI7xI";
$xml = simplexml_load_string($string_data);
$citta = (string) $xml->result[0]->address_component[3]->long_name;
echo "<p>".$citta."</p>";

Answer 1

You are missing geoname in $xml-> name;
Try it like this:
$xml = simplexml_load_string($string_data);
$citta = (string)$xml->geoname->name;
echo $citta;
Demo Php
If you want to loop through mulitple items you could use:
foreach ($xml->geoname as $item) {
echo $item->name;
}
Update:
For the updated part you could use the same technique:
$xml = simplexml_load_file("https://maps.googleapis.com/maps/api/geocode/xml?latlng=41.51,15.16&key=AIzaSyClG_vc2nkQCzXqvDzW1maPrUWLyADI7xI");
foreach ($xml->result as $item) {
if ((string)$item->type === "administrative_area_level_3") {
echo $item->address_component->long_name;
}
}
Or by index [1]:
echo $xml->result[1]->address_component->long_name;
