You can extract the soap Body using XMLParser.

First convert your xml into NSData and call the parser to parse it.

    //converting into NSData
    NSData* data = [theXML dataUsingEncoding:NSUTF8StringEncoding];

    //initiate  NSXMLParser with this data
    NSXMLParser *parser = [[NSXMLParser alloc] initWithData:data];

    //setting delegate
    parser.delegate = self;

    //call the method to parse
    BOOL result = parser.parse;

    parser.shouldResolveExternalEntities = true;

Now, you need to implement the NSXMLParser delegate into your class.

-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary<NSString *,NSString *> *)attributeDict {
currentElement = elementName;
NSLog(@"CurrentElementl: [%@]",elementName);

}

-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
NSLog(@"foundCharacters: [%@]",string);

}

You will find the value under key of your xml.

Do not forget to add NSXMLParserDelegate into your class interface.
