Question

Does anyone have some idea how to parse the following xml using event-driven model NSXMLParser class?

   Main 
  

        

Answer 1

A very easier way to solve it than the accepted answer, for short XML files:

XML example:

    
            50058
            -0.16
    
    
            3.4610
            +0.29
    
    
            3.7673
            -0.25

Implement a counter:

@implementation className{
    int parserCounter;
}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
    parserCounter++;

    NSLog(@"%d: %@",contadorParser,string);

    if (parserCounter == 3) doAnythingFor3;
    if (parserCounter == 5) doAnythingFor5;
    if (parserCounter == 9) doAnythingFor9;
    if (parserCounter == 11) doAnythingFor11;
    if (parserCounter == 15) doAnythingFor15;
    if (parserCounter == 17) doAnythingFor17;
    if (parserCounter == 20) doAnythingFor20;

}

How will i know witch number is witch node ? By seeing the log. It will be something like:
