    	<template id="abcd3" src="template1.pdf" />
    	<template id="abcd4" src="template1.pdf" />
	</templates>
	
	<category title="Hello World">

Sample code to parse this

#import "SGPullParser.h"

NSMutableDictionary *_templates = [NSMutableDictionary dictionaryWithCapacity:5];
NSMutableDictionary *_categories = [NSMutableDictionary dictionaryWithCapacity:5];
NSData* data = ...

SGPullParser *parser = [SGPullParser parserWithData:data];
while ([parser readElement]) {

	// Using C strings saves unnecessary copy operations
	if ([parser elementHasNameC:"template"]) {
	
		// Of course you can use NSString objects as well
        NSString *identifier = [parser attributeWithQName:@"id"];
        NSString *src = [parser attributeWithQNameC:"src"];
        
        [_templates setObject:src forKey:identifier];
    } else if ([parser elementHasNameC:"category"]) {
        NSString *title = [parser attributeWithQNameC:"title"];
        NSMutableArray *links = [NSMutableArray arrayWithCapacity:10];
        
        // Run this loop until we reach the end of category 
        while ([parser readElementUntilC:"category"])
            if ([parser elementHasNameC:"media"]) {
                NSDictionary *media = @{@"name" : [parser attributeWithQName:@"name"],
                							@"src" : [parser attributeWithQName:@"src"]};
                
                [links addObject:media];
            }
        
        [_categories setObject:links forKey:title];
    }
 }
