TouchXML - reading into an object

[elephant85]

Hey everyone,

So I have an XML file and am using TouchXML to read it. There are only some elements in the XML file that I require.
So I created a class 'Contact' with properties that I wish to save from the XML file.
What i've come up with so far is this:

	NSMutableArray *res = [[NSMutableArray alloc] init]; 
	CXMLDocument *doc = [[[CXMLDocument alloc] initWithData:data options:0 error:nil] autorelease]; 
	NSArray *nodes = nil; 
	
	//! searching for item nodes 
	nodes = [doc nodesForXPath:@"/statuses/status/user" error:nil]; 


	for (CXMLElement *node in nodes) 
	{ 
		int counter; 

		Contact *contact  = [[Contact alloc] init]; 
		for (counter = 0; counter < [node childCount]; counter++) 
		{ 
			//pulling out name and description only for the minute!!!
			if ([[[node childAtIndex:counter] name] isEqual:@"name"]){

				contact.name = [[node childAtIndex:counter] stringValue];
				
			}else if ([[[node childAtIndex:counter] name] isEqual:@"description"]) {
				
				// common procedure: dictionary with keys/values from XML node 
				if ([[node childAtIndex:counter] stringValue] == NULL){
					contact.nextAction = @"No description";
				}else{
					contact.nextAction = [[node childAtIndex:counter] stringValue];
				}
				
			}else if ([[[node childAtIndex:counter] name] isEqual:@"created_at"]){
				NSString *str = [[NSString alloc] init];
				str = [[node childAtIndex:counter] stringValue];
				contact.date = str;
				[str release];
			}else if([[[node childAtIndex:counter] name] isEqual:@"time_zone"]){
				
				contact.status = [[node childAtIndex:counter] stringValue];
				[res addObject:contact];
				[contact release];
			}
		} 
	}
	self.contactsArray = res;
	[res release];
	[self.tableView reloadData];

However I have some concerns... I'm not to sure about the creation of the object and its release... I think it might be causing me memory problems but I've tried a few different ways of doing this and haven't been able to find a solution.
Can somebody tell me if what i'm doing is completely wrong? or is there another/better way of doing it.

Thanks in advance,
Fiona
