thank you in advance

Just throwing usual advice: this sounds like missing retain somewhere. — jv42
thank u for reply, i analysis my code but retain is not case ...still confuse where is the problem — Pooja
Can you add the piece of code you use to parse? It seems like you are sending a message (calling method) which is not recognized by the object you send it to... — MiKL
@MiKL, following is code also i am using synchronous NSURL -- NSError *error; NSURLResponse *response; NSData *urlData=[NSURLConnection sendSynchronousRequest:req returningResponse:&response error:&error]; webData =[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding]; if (xmlParser) { [xmlParser release]; } xmlParser = [[NSXMLParser alloc] initWithData:webData]; [xmlParser setShouldResolveExternalEntities:YES]; [xmlParser setDelegate: self]; [xmlParser parse]; — Pooja
@MiKL, i just try to use "urlData" instead of webData in xmlParser = [[NSXMLParser alloc] initWithData:urlData]; and now it parse very well ... — Pooja
