Parse multiple XML files to separate UITableViews-question

[CanadaDev]

My app is made up of a TabBarController, each tab has a seperate UITableView.

On launch I parse an XML file from my server into an Object class and then display the objects in the tableview.

My question is, what do I do when I want to parse a second XML file? Currently, when doing so, the information in XML file2 will overwrite the objects parsed by XML file1. How do I go about this? Do I set up another Object class to hold the second array of information from XML file2 or is there another to work around the issue?

Thanks
