使用NSXMLParser根据属性解析XML

Question

I would like to parse xml according to their attributes and saved as dictionary .

the xml output seems like that

<Tracking event="firstElement">
http://www.firstElement.com
</Tracking>

What i am doing right now is :

Getting tag name which is Tracking and saving URL. But in final , which URL linked event method is unknown.

I have to be save it on NSDictionary and call it like that :

[dictionary objectForKey:@"firstElement"];

-> (NSURL *) http://www.firstElement.com

How can i be achieve ? Best Regards ..

You can get event in NSXMLParserDelegate:

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
    // reset temp data
    [self.mutableData setString:@""];

    if([elementName isEqualToString:@"Tracking"]) {
        NSString *event = [attributeDict objectForKey:@"event"];
    }
}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
    [self.mutableData appendString:string];
}

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
    if([elementName isEqualToString:@"Tracking"]) {
        NSString *URL = [NSString stringWithFormat:@"%@", self.mutableData];
    }
}

parse to get URL and set dictionary with @{event:URL}

mutableData is property MutableString

@property (nonatomic) NSMutableString *mutableData;

Hope this help you :)
