Going from your code, you are trying to access the XML feed at "http://weather.co.ua/xml/feed.xml?version=1.1&city;=1310&dayf=5"

If you go there, you get an error "XML001 Main input params not found". The reason the XML parser is throwing you an error is because the DOM tree doesn't exist. Fix your feed link and that should sort problems out.

The problem I'm getting is that the xml only has 20 days, so after that the xml is empty =)

Try replacing
Code:
for($i=0;$i<24;$i++) {

for
Code:
$times = count($xml->forecast->day);
for($i=0;$i<$times;$i++) {

@avinashv: I think it is city= and not city;=... probably a forum problem
