Your removeRows looks ok. I guess you're either telling the treeview (by
false row number) that it should remove the last row, or your data
method doesn't fetch the proper row from the document.
As you use QDomDocument, your complete model is probably not that large,
can you post a complete example, or at least the complete model
including QDomItem.
