Trying again!!

[nacho2]

Hi everyone, I posted this question but got no answer, can somebody help me out!!??

I'm trying to update my xml database.

I have a table called Clients (columns: Id, Name,..., Erased), and I'm trying to modify the column Erased from False to True (yes it is a boolean column).

I only want to modify the dataset and then run dataset.writexml, there is no sql database or any other external database.

I know there is a command dataset.select() for selecting rows but isn't there anything for updating??? (changing one value of one column of one row)

Erasing a column and then adding the changed one won't work because the database won't let me because there are table relations and erasing one would be incoherent. And adding the row first and then erasing the old one won't work either because Id is a primary key and is unique.

Thanks for your help!!!
