Question

I Converted NSData to string then I am getting the string like below, Now I want to parse this one. If parse with json serilazation I am getting json data nil.
<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><EmployeesLoginMethodResponse xmlns="http://tempuri.org/"><EmployeesLoginMethodResult>[{"sms":"You have logged in successfully!","userId":"29","type":"1","name":"mng 56 78"}]</EmployeesLoginMethodResult></EmployeesLoginMethodResponse></soap:Body></soap:Envelope>
If I parse using XML I am Getting The String Like below,In this How to get value of sms,userId,name
[{
"sms": "You have logged in successfully!",
"userId": "13",
"type": "1",
"name": "Suhashini Kumari Singh"
}]
Here is my code
NSString *urlString=[NSString stringWithFormat:#"http://workforce.wifisocial.in/WebServicesMethods/EmployeesWebService.asmx"];
NSString* webStringURL = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL* url = [NSURL URLWithString:webStringURL];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSString* requestBody =[NSString stringWithFormat:#"<?xml version=\"1.0\" encoding=\"utf-8\"?><soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\"><soap:Body><EmployeesLoginMethod xmlns=\"http://tempuri.org/\"><username>\%#</username><password>\%#</password><IpAddress>\%#</IpAddress><deviceName>\%#</deviceName></EmployeesLoginMethod></soap:Body></soap:Envelope>",self.userNameTextFiled.text,self.passwordTextField.text,ipAddress,deviceName];
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:#"text/xml" forHTTPHeaderField:#"Content-type"];
[request setValue:#"\"http://tempuri.org/EmployeesLoginMethod\"" forHTTPHeaderField:#"SOAPAction"];
[request setHTTPBody:[requestBody dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]] ;
NSError *error;
NSHTTPURLResponse *response = nil;
NSData * urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(#"Response code: %ld", (long)[response statusCode]);
NSString* responseString = [NSString stringWithUTF8String:[urlData bytes]];
NSLog(#"%#",responseString);
if (urlData)
{
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:urlData options:0 error:&error];

Answer 1

Please try XMLDictionary library. For more reference https://github.com/nicklockwood/XMLDictionary
Just convert your NSData to NSDictionary using XMLDictionary as below
NSDictionary *xmlDictionary = [NSDictionary dictionaryWithXMLData:returnData];

Answer 2

If you got you response in json string then try like below,
NSError *jsonError;
NSData *objectData = [responseString dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData
options:NSJSONReadingMutableContainers
error:&jsonError];
here responseString is final output json string that you have posted in question.
Then fetch data from json dictionary.
If this scenario will not work then take a look at NSXMLParser, you can refer Appcoda's tutorial.

Answer 3

It's nil because it's not the JSON parsing that's failing but because of the conditional type cast of the resulting object as a dictionary.
It's an array with one item which is dictionary. So, during parsing cast it as a NSArray.
Like,
Instead of:
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:urlData options:0 error:&error];
Use:
NSArray *arrJson=[NSJSONSerialization JSONObjectWithData:urlData options:0 error:&error];
NSDictionary *json = [arrJson objectAtIndex:0];
NSString *sms=[json valueForKey:#"sms"];
NSString *userId=[json valueForKey:#"userId"];
NSString *type=[json valueForKey:#"type"];
NSString *name=[json valueForKey:#"name"];

You can use XML to JSON converter (XMLReader)
: https://github.com/amarcadet/XMLReader
#import "XMLReader.h"
Here is the sample snippet for your code :
NSData * urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
if (urlData)
{
NSDictionary *dict = [XMLReader dictionaryForXMLData:urlData error:&error];
NSLog(#"-----%#-----",dict);
NSError *jsonError;
NSString *json2 = [[[[[[dict valueForKey:#"soap:Envelope"] valueForKey:#"soap:Body"] valueForKey:#"EmployeesLoginMethodResponse"] valueForKey:#"EmployeesLoginMethodResult"] valueForKey:#"text"] stringByReplacingOccurrencesOfString:#"\"" withString:#"\""];
NSData *objectData1 = [json2 dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *json1 = [NSJSONSerialization JSONObjectWithData:objectData1 options:NSJSONReadingMutableContainers error:&jsonError];
NSLog(#"-----%#-----",json1);
}
