iPhone parsing XML humanly

Tired of struggling with NSXMLParser, I decided to write my own class, which using it returns data in the form of NSMutableDictionary, in a pleasant form for a person. Accordingly, anyone who wishes may modify it for themselves.


The result of the parser will be an NSMutableDictionary of the following form:
Dictionary:
key: "parentNode" value: (NSMutableDictionary*) //
key: "name" value: (NSString*) //
key: "attributes" value: (NSDictionary*) //
key: "childs" value: (NSMutableArray*) // NSMutableDictionary
key: "content" value: (NSString*) // CDDATA


You can use as follows:

XMLParser * myParser = [[XMLParser alloc]init];
[myParser setDelegate(self)];

if (![myParser parseUrl: @"http://....xml" )
{
NSLog( @"Some error" );
}

, :

-( void )parseFinished:(id) parser result:(NSMutableDictionary*) rootNode
{
...
}

#import <Foundation/Foundation.h>

@ interface XMLParser : NSObject {

NSMutableDictionary * currentNode;
id<XMLParserProtocol> delegate ;
