i am trying to use this code 

//  we will put parsed data in an a array
    NSMutableArray *res = [[NSMutableArray alloc] init];

    //  using local resource file
    NSString *XMLPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"20137_ZZ Pizza & Kabob_2013_04_19 01_20_22_Local.xml"];
    NSData *XMLData   = [NSData dataWithContentsOfFile:XMLPath];
    CXMLDocument *doc = [[[CXMLDocument alloc] initWithData:XMLData options:0 error:nil] autorelease];

    NSArray *nodes = NULL;
    //  searching for piglet nodes
    nodes = [doc nodesForXPath:@"//MenuCatID" error:nil];

    for (CXMLElement *node in nodes) {
        NSMutableDictionary *item = [[NSMutableDictionary alloc] init];
        int counter;
        for(counter = 0; counter < [node childCount]; counter++) {
            //  common procedure: dictionary with keys/values from XML node
            [item setObject:[[node childAtIndex:counter] stringValue] forKey:[[node childAtIndex:counter] name]];
        }

        //  and here it is - attributeForName! Simple as that.
        [item setObject:[[node attributeForName:@"id"] stringValue] forKey:@"id"];  // <------ this magical arrow is pointing to the area of interest

        [res addObject:item];
        [item release];
    }

    //  and we print our results
    NSLog(@"%@", res);
    [res release];

In my opinion, KissXML is better for you https://github.com/robbiehanson/KissXML

Here is example how to parse your XML file

// your file name
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"filename" ofType:@"xml"];

// load file content into string
NSString *xmlContent =  [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];

// create XMLDocument object
DDXMLDocument *xml = [[DDXMLDocument alloc] initWithXMLString:xmlContent options:0 error:nil];

// Get root element - DataSetMenu for your XMLfile
DDXMLElement *root = [xml rootElement];

// go through all elements in root element (DataSetMenu element)
for (DDXMLElement *DataSetMenuElement in [root children]) { 
    // if the element name's is MenuCategories then do something
    if ([[DataSetMenuElement name] isEqualToString:@"MenuCategories"]) {
        // get MenuCatID
        NSInteger MenuCatID = [[[DataSetmenuElement elementForName:@"MenuCatID"] objectAtIndex:0] integerValue];
    }
}

Method elementForName will get you NSArray of all elements with specific name (if you want first then objectAtIndex:0) and thereafter you have to specific type (integerValue, stringValue, doubleValue)

I hope this helps.
