XMl parsing condtions

Question

HI, all, i am not sure how to write if and else condition in order to parse xml. this is how my returned xml looks like this.

<?xml version="1.0"?>
<a><a1>A</a1></a>
<b><b1>B</b1></b>
<c><c1>C</c1></c>
<d><d1>D</d1></d>
<e><e1>E</e1></e>
<f><f1>F</f1></f>
<g><g1>G</g1></g>

i tried various condition, but i am not able to properly navigate through each node.

How should i write if / else condition in

"-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qName
   attributes: (NSDictionary *)attributeDict
{
//if and else condition here

if([elementName isEqualToString:@"a"]) {
}
else if([elementName isEqualToString:@"b"]) {

 }
…………
}"

and "-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {}"

and finally in here

"-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
//if else condition here
if([elementName isEqualToString:@"a"]) {
}
else if([elementName isEqualToString:@"b"]) {

 }

……
}
"

i need to pass the returned values from xml like, A,B,C to NSSTring for further programming..but i am not even able to parse it.

thanks Suggestions are always appreciated

As always, the documentation on NSXMLParser is excellent. What you probably want to do is implement the delegate method parser:foundCharacters: and accumulate the text inside your nodes (i.e., with an NSMutableString). didStartElement: and didEndElement: will tell you when you enter and exit elements, as you already know. From there it's just a matter of storing the text in a suitable data structure for further processing.
