Parse/Display XML from a POST Method

Question

Ok,so on my iOS app I have a HTTP Post method that returns xml, like this

<?xml version="1.0" encoding="utf-8"?>
<geocode>
    <suburb>Sydney</suburb>
    <state>NSW</state>
</geocode>

It returns through a HTTP POST method that gets the Latitude and Longtitude

What I what to do is display this XML on a button or on a label. But not the code just like Bold Sydney and less for NSW. I have the code saved as

NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *strdata=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];

So I usually call on the strdata to get the XML but it displays it in its code form and thats the problem. I looked at using NSXMLParser but I couldnt figure out how to use it.

What are you trying to do ? What happened when you use NSXMLParser ? — Midhun MP, Dec 11 '13 at 05:25
I couldnt figure out where to put it for one and I didnt know whether it needed another framework or what it needed. — user3089637, Dec 11 '13 at 05:36

Declare a property like:

@porperty (nonatomic, strong) NSXMLParser  *parser;

And Implement a method like:

- (void)parseXML
{
   NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
   _parser = [[NSXMLParser alloc] initWithData:urlData];
   [_parser setDelegate:self];
   [_parser parse];
}

And implement the following NSXMLParser Delegate methods:

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName

Where am I meant to place the Delegate methods, In the `AppDelegate.m/.h` files? – user3089637 Dec 11 '13 at 05:57
@user3089637: No in the same file where you are adding the parser. Please check the tutorial for more info. – Midhun MP Dec 11 '13 at 05:58
http://i.imgur.com/r6UIJIj.png I did the tutorial but I'm only supposed to have one result spanning of state and suburb and then display that result formatted/parsed on a label/button. I also have an error that is that photo. – user3089637 Dec 11 '13 at 06:22
@user3089637: did you check my answer I used _parser not parser also not use `@synthesize parser;` – Midhun MP Dec 11 '13 at 06:45
Synthesizing it asked to change all the `_parser` to `parser`. So all good. – user3089637 Dec 11 '13 at 23:35
Wait so how do I display the parsed XML? – user3089637 Dec 11 '13 at 23:36
