Need help with editing XML files in ASP.NET 2

Hi everybody

I have many well working web forms in ASP.NET1, which work with XML files. Most of the web forms use SORT, EDIT, DELETE, UPDATE etc. Recently I Installed framework 2 and thought it will make my life easier with XML. There is so much written on GridView and XMLDatasource, that we will not need to write code for edit and so on, but unfortunately I cannot find out how. I cannot even bind my xml files to XMLDatasource as i have then in the following format:
<row>
<column>AAA</column>
<column>BBB</column>
</row>
but strange that, if I change it to
<row column1="AAA" column2="BBB" ...></row>
then XMLDatasource atleast displays my data.

SO, my question is, what is the best way for working with XML files in ASP.NET2 I need to use EDIT, UPDATE etc. and I do also have comments in my XML files, whcih will be deleted, if i use DATASET to read and write to XML files.
Thanks in advance
