I'm new to iOS dev, but I'd like to solve this problem: I have an XML feed - http://www.navigant.com/services/professionals.ashx - that I would like to parse and put into a tableView in my application. The table view is housed within a tab bar application, which is the rootViewController. I'd like to have the information drill-down, as in this line of logic... Industry -> Location -> Professionals List -> Professionals Details All of the samples that I have found feature a navigation controller as the rootViewController, which is throwing me off. I've tried to get the XML feed functioning on its own, but I can't quite get the logic right. Any help would be greatly appreciated Thanks!
