Get the XML content with AFNetworking library

Question

now i would like use AFNetworking library to get XML content, so I use this code

AFXMLRequestOperation *operation = [AFXMLRequestOperation XMLParserRequestOperationWithRequest:request 
success:^(NSURLRequest *request, NSHTTPURLResponse *response, NSXMLParser *XMLParser) 
{
    XMLParser.delegate = self;
    [XMLParser parse];
} 
failure:nil];
[operation start];

my question is to know if there is any way to get the content of the xml response ( i want to print the xml content with NSLog )

thanks in advance

The raw data from the request is always available in the responseData property of the operation class. Here is how you would show it with NSLog:

__block AFXMLRequestOperation *operation = [AFXMLRequestOperation XMLParserRequestOperationWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://legalindexes.indoff.com/sitemap.xml"]] success:^(NSURLRequest *request, NSHTTPURLResponse *response, NSXMLParser *XMLParser) {
    NSLog(@"Parser: %@", XMLParser);
    NSLog(@"Raw XML Data: %@", [[NSString alloc] initWithData:operation.responseData encoding:NSUTF8StringEncoding]);
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, NSXMLParser *XMLParser) {
    NSLog(@"Failure!");
}];

[operation start];

That said, the standard AFXMLRequestOperation class uses NSXMLParser which is painful to use. If your payload isn't too big and performance isn't an issue, I suggest you use Mattt's new AFKissXMLRequestOperation class which will do the parsing for you and expose a friendlier NSXMLDocument compatible object:

__block AFKissXMLRequestOperation *operation = [AFKissXMLRequestOperation XMLDocumentRequestOperationWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://legalindexes.indoff.com/sitemap.xml"]] success:^(NSURLRequest *request, NSHTTPURLResponse *response, DDXMLDocument *XMLDocument) {
    NSLog(@"XMLDocument: %@", XMLDocument);
    NSLog(@"Raw XML Data: %@", [[NSString alloc] initWithData:operation.responseData encoding:NSUTF8StringEncoding]);
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, DDXMLDocument *XMLDocument) {
    NSLog(@"Failure!");
}];

[operation start];
