I am new to iPhone programming, and this is the first time parsing XML file. I have added the url and also hardcoded the XML file into the string, however I am not getting the correct response from the server.

Here is my code:

NSString *post = @"<?xml version=\"1.0\"encoding=\"UTF-8\"?<request><call>GetNewChapters</call><udid>1000000000000000000000000000000000000000</udid><book_id>1</book_id><updatetoken>B20100125054802</updatetoken></request>";

NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

NSURL *url=[NSURL URLWithString:@"https://www.paisible.com/babelle_api"];

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];    
[request setHTTPBody:postData];



NSString *myStr = [[NSString alloc] initWithData:postData encoding:NSUTF8StringEncoding];
NSLog(@"String Value :%@",myStr);


NSLog(@"theRequest: %@", request);
NSURL *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if(theConnection)
{
    webData = [[NSMutableData data] retain];
}
else
{
    NSLog(@"theConnection is NULL");
}

Where as webdata is NSMutable data. Please let me know what errors I have made in my parsing code.

  • What is the response you are getting? I think you havent pasted/written the delegate methods for getting the response. Commented Feb 23, 2011 at 7:03

Reset to default

Try to replace 

NSURL *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

with the following:

NSURLResponse *resp;
NSError *error;
NSMutableData *webData = [NSURLConnection sendSynchronousRequest:request returningResponse:&resp error:&error];

Than, check what "webData" contains.
