XML-ből adatok php tömbbe

Innen szeretném kinyerni az időjárás adatokat:

Az alábbi kód nem ad vissza semmit.
Hol a hiba?

Elsőnek kérd le a tartalmat pl. file_get_contents()-el majd azt add át az xml2array-nek:

$content = file_get_contents("http://xml.weather.yahoo.com/forecastrss?u=c&p=".$LOCID); $xml = xml2array($content); print_r($xml);
