You mean something like this

NSURL *URL = [NSURL URLWithString:
              [URLString stringByAddingPercentEscapesUsingEncoding:
               NSASCIIStringEncoding]];


NSData *dataXML = [NSData dataWithContentsOfURL:URL];

NSString *applicationDocumentsDir = 
[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *storePath = [applicationDocumentsDir stringByAppendingPathComponent:@"sample.xml"];
[dataXML writeToFile:storePath atomically:TRUE];
    NSData *contenuto = [NSData dataWithContentsOfFile:storePath];
    NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:contenuto]
