How to parse SOAP xml response in iPhone programming - ios

Question

I am unable to parse soap response,I have tried many ways but not solved my problem,I need the value of USERNAME and PASSWORD.
I am getting following response after soap request :
<?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>
<AuthenticateResponse xmlns="http://tempuri.org/">
<AuthenticateResult>
<DocumentElement>
<Status>
<USERNAME>True</USERNAME>
<PASSWORD>true</PASSWORD>
</Status>
</DocumentElement>
</AuthenticateResult>
</AuthenticateResponse>
</soap:Body>
</soap:Envelope>
Here is my code :
-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qName attributes: (NSDictionary *)attributeDict
{
if ( [elementName isEqualToString:#"AuthenticateResponse"]||[elementName
isEqualToString:#"AuthenticateResult"] || [elementName isEqualToString:#"DocumentElement"])
{
statusArray = [[NSMutableArray alloc] init];
}
else if ([elementName isEqualToString:#"Status"])
{
authenticate = [[Authenticate alloc] init];
}
else if ([elementName isEqualToString:#"USERNAME"])
{
currentElementValue = [[NSMutableString alloc] init];
}
else if ([elementName isEqualToString:#"PASSWORD"])
{
currentElementValue = [[NSMutableString alloc] init];
}
}
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
if (currentElementValue)
{
[currentElementValue appendString:string];
}
}
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI: (NSString *)namespaceURI qualifiedName:(NSString *)qName
{
if( [elementName isEqualToString:#"USERNAME"])
{
authenticate.userName = currentElementValue;
}
else if ([elementName isEqualToString:#"PASSWORD"])
{
authenticate.strAuthenticate = currentElementValue;
}
else if ([elementName isEqualToString:#"Status"]) {
[statusArray addObject:authenticate];
}
}
How can i get the values of username and password,can someone help me to parse this.
Thanks in advance.

Answer 1

Try this:
Add 2 properties to your class.
#property (nonatomic, strong) NSString *elementValue;
#property (nonatomic, strong) NSMutableArray *authenticationValues;
Replace your current implementation by:
- (void)parseXML:(NSData *)xmlData {
self.authenticationValues = [NSMutableArray array];
NSXMLParser *parser = [[NSXMLParser alloc] initWithData:xmlData];
parser.delegate = self;
[parser parse];
NSLog(#"Authentication values: %#", self.authenticationValues);
}
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
// Keep track of the current element value
self.elementValue = string;
}
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
// If the element was 'username' or 'password', add the value to the authenticationValues array
if ([elementName isEqualToString:#"USERNAME"] ||
[elementName isEqualToString:#"PASSWORD"]) {
[self.authenticationValues addObject:self.elementValue];
}
}
To parse the file perform the method parseXML:
When running this you should see the following output on the console:
Authentication values: (
True,
true
)
which are the values for USERNAME and PASSWORD.

Please see the demo prepared for iOS/OSX using sample web service.
It uses swift - SOAP request creator & response parser.

Done using Alamofire & SWXMLHash library
