This my post metod:-
NSString *soapMessage = [NSString stringWithFormat:
@"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
"<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/\">\n"

"</AuthenticationHeader>\n"
"</soap:Header>\n"
"<soap:Body>\n"
"<GetAllAlerts xmlns=\"Medtech/MMHWebservices/ExternalDeviceData\" />\n"
"</soap:Body>\n"
"</soap:Envelope>\n",userName,passWord];
// NSUserDefaults *default2 = [NSUserDefaults standardUserDefaults];

NSURL * url = [NSURL URLWithString:@"http://192.168.2.119/ManageMyHealthWebService/ExternalApplicationService.asmx"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
[theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue: @"Medtech/MMHWebservices/ExternalDeviceData/GetAllAlerts" forHTTPHeaderField:@"SOAPAction"];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *theConnection =
[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if( theConnection )
{
webData = [NSMutableData data] ;
NSLog(@"Problem%@",webData);
}
else
{
NSLog(@"theConnection is NULL");
}
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSLog(@"DONE. Received Bytes: %d", [webData length]);
NSString *theXML = [[NSString alloc] initWithBytes:[webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding];

//
// NSLog(@">>>>>>%@",myData);
self.xmlParser = [[NSXMLParser alloc] initWithData:webData];
[self.xmlParser setDelegate:self];
// [self.xmlParser setShouldProcessNamespaces:NO];
// [self.xmlParser setShouldReportNamespacePrefixes:NO];
// [self.xmlParser setShouldResolveExternalEntities:NO];
[self.xmlParser parse];
// Run the parser
[self.xmlParser parse];
if ([self.xmlParser parse])
{
NSLog(@"XML parsing was successful");
//dispatch_async(dispatch_get_main_queue(), ^{
//reload the data in the table view
[self.remindTable reloadData];
// });
}
else{
NSLog(@"XML parsing failed");
}
NSLog(@"Parse Error: %@", [self.xmlParser parserError]);
}
I am getting the response in below format
