Question

i made iPad application, i want to fetch data from this url,

http://ipad.idealake.com/stockquote.aspx?id=SBIN

and i want to store this data into string,

so i written this, but it doesn’t take data into the string,

    NSURL *urlq=[NSURL URLWithString:str1];
    NSURLRequest *reqq=[NSURLRequest requestWithURL:urlq];
    [webViewq loadRequest:reqq];


mainstr=[[NSMutableString alloc] initWithContentsOfURL:urlq encoding:NSUTF32StringEncoding error:NULL];

-(void)fire{

NSString *URL = @"http://ipad.idealake.com/stockquote.aspx?id=SBIN";
    NSURLRequest *rq = [NSURLRequest requestWithURL:[NSURL URLWithString:URL]];
    conn1 = [[NSURLConnection alloc] initWithRequest:rq delegate:self];
    webData = [[NSMutableData data] retain];
}


-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
    [webData setLength: 0];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
    [webData appendData:data];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
    NSLog(@"ERROR with theConenction");
    [connection release];
    [webData release];
}

-(void)connectionDidFinishLoading:(NSURLConnection *)connection {
    NSString *theResult = [[NSString alloc] initWithBytes: [webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding];
    NSLog(@"xml : %@",theResult);
}
