Get the entire XML downloaded data - afnetworking

Question

I have an outdated application which use to download an XML document and parse it on the iPhone app, I used the NSURLConnection for that purpose:
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
//NSLog(#"Response :%#",response);
responseData = [[NSMutableString alloc] init];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
NSString *str = [[NSString alloc] initWithData:data
encoding:NSASCIIStringEncoding];
[responseData appendString:str];
[str release];
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSLog(#"DATA : %#",responseData);
if (responseData != nil) {
[self startParsing:responseData];//Parse the data
[responseData release];
}
}
Since moving to use NSXMLParserDelegate with AFXMLRequestOperation, I cannot figure out a way to get xml data properly:
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
[responseData appendString:elementName];
[responseData appendString:namespaceURI];
[responseData appendString:qName];
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{
[responseData appendString:string];
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{
[responseData appendString:elementName];
[responseData appendString:namespaceURI];
[responseData appendString:qName];
}
-(void) parserDidEndDocument:(NSXMLParser *)parser{
[SVProgressHUD showSuccessWithStatus:#"Downloading completed"];
NSLog(#"DATA : %#",responseData);//not properly appended, tags delimeters are missing
if (responseData != nil) {
[self startParsing:responseData];
[responseData release];
}
}
How to append all the data received from the server in the responseData mutable string ? I debugged the data received after finishing downloading and the xml is missing tags delimeters <>. I think I ma missing the way to get the xml data.
P.S: Please note it's important that I get the xml in a NSMutableString object.

I used AFURLConnectionOperation as you recommended, it works fine with my purpose, but I noticed that my received data is not catched by the delegate methods, instead I can get the data in a completion block:
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:API_URL]];
AFURLConnectionOperation *operation = [[AFURLConnectionOperation alloc] initWithRequest:request];
operation.completionBlock = ^{
NSLog(#"Complete: %#",operation.responseString);//responseString is my data
};
[operation start];
[SVProgressHUD showWithStatus:#"Downloading files"];
wo since NSURLConnection delegate methods are not called, how can I manage failure, etc? Thanx.

AFXMLRequestOperation is explicitly intended to be used to return you an NSXMLDocument instance, NOT a raw XML string.
If you want the XML string use AFURLConnectionOperation and build the NSMutableString the same way you do with NSURLConnection.
