xml parsing iphone issue

Question

I'm using the NSXMLParser however i dont quite understand how to display items from a xml correctly. E.g. i have this in the xml parser:

- (void) parser:(NSXMLParser *)parser
didStartElement:(NSString *)elementName
   namespaceURI:(NSString *)namespaceURI
  qualifiedName:(NSString *)qName
     attributes:(NSDictionary *)attributeDict
{
    if ([elementName isEqualToString:@"level4"]) {
        //add a book object to the array at the index determined by bookCount
        self.bookCount++;
        [books addObject:[[book alloc]init]];
        //[books insertObject:[[book alloc]init] atIndex:self.bookCount];
    }   
    if ([elementName isEqualToString:@"module"]) {
        isFirstName = YES;
    }
    if ([elementName isEqualToString:@"moduleTitle"]) {
        isLastName = YES;
    }
    if ([elementName isEqualToString:@"semester"]) {
        isTitle = YES;
    }
    if ([elementName isEqualToString:@"assessmentName"]) {
        isGenre = YES;
    }
}

This is my xml

<myCourse>
    <courseName>BEng Mobile and Web Computing</courseName>
    <courseStructure>
        <level4>
            <module>
                <moduleCode>ECSC401</moduleCode>
                <moduleTitle>Programming Methodology</moduleTitle>
                <credits>15</credits>
                <semester>1</semester>
                <assessmentDetails>
                    <assessment>
                        <assessmentName>Test1</assessmentName>
                        <assessmentType>Coursework</assessmentType>
                        <assessmentWeighting>30</assessmentWeighting>
                        <assessmentDueDate/>
                    </assessment>
                    <assessment>
                        <assessmentName>Coursework</assessmentName>
                        <assessmentType>Coursework</assessmentType>
                        <assessmentWeighting>40</assessmentWeighting>
                        <assessmentDueDate/>
                    </assessment>
                    <assessment>
                        <assessmentName>Test2</assessmentName>
                        <assessmentType>Coursework</assessmentType>
                        <assessmentWeighting>30</assessmentWeighting>
                        <assessmentDueDate/>
                    </assessment>
                </assessmentDetails>
            </module>
        </level4>
    </courseStructure>
</myCourse>

(it continues level 1,level2,level3 using the same format). I simply want to display all the modules under the 'level4' hierarchy - how can i do this?/what am i doing wrong? the items are displaying just not the right ones ..

First of all you have to create one NSMutableDictionary. When you get the tag in didStartElement Method initiate this Dictionary.And also set one flag.

And in Found character method check that flag, if It is then store that tagValues and in didEndElement store all the values in this Dictionary when you find .

You can find all levels values using this. Hope this will help you.

Use both methods:

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

and

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

For parsing.
