Do not display another row in the table when status equals "Canceled"

I have a <p:dataTable> that is populated by data that is in a .xml file and I have in front of each line a button to end or cancel the process. How do I not to display more in my DataTable the process that was canceled. Can you exclude all column-related tags from the xml file? or it would be simpler every time I click cancel it would change the status in the file .xml to canceled so I could make a condition to not display it. Can anyone help?
