Unable to read xml file

Question

There was a small problem getting the contents of the xml file (using TouchXML).

My first request works very well, looks something like this:

NSString *url = [NSString stringWithFormat:STATION_ID, latitude, longtitude];
CXMLDocument *rssParser = [[CXMLDocument alloc] initWithContentsOfURL:[NSURL URLWithString:url] options:0 error:nil];
NSLog(@"%@",rssParser);

so this log gives me the full xml file.

after that, in another method, I try to do the same:

NSString *url = [NSString stringWithFormat:WEATHER_URL, [positionInformation objectForKey:@"stationId"]];
CXMLDocument *rssParser = [[CXMLDocument alloc] initWithContentsOfURL:[NSURL URLWithString:url] options:0 error:nil];
NSLog(@"%@", rssParser);

but getting log im (null). The Loggin URL String gives me the correct URL without spaces or anything else, for example, the URL looks like this:

NSString *url = [NSString stringWithFormat:WEATHER_URL, [positionInformation objectForKey:@"stationId"]];
NSLog(@"%@", url);

Result in the debugger console

http://api.wunderground.com/weatherstation/WXCurrentObXML.asp?ID=KCASUNNY19

viewing this file with my browser seems to be in order. Does anyone know what is going wrong ?????

I also tried first getting the contents of this url using stringWithContentsOfURL, but that didn't work either.

Are you sure your URL string is correctly encoded so that the question mark is interpreted as a request? You might want to look at usage dataUsingEncodingor stringUsingEncodingat your URL before using it for initialization rssReader.
