how to insert a DataRow into a DataSet?

Hello!

I have next data in my xml file:

<myData>
<node>
 <first>one</first>
 <second>
  <myInt0>34</myInt0>
  <myInt1>24</myInt1>
  <myInt2>27</myInt2>
 </second>
 <third>three</third>
</node>
</myData>

I need to insert one more "node". I have next code:

DataRow d_f = ds.Tables[ "node" ].NewRow();
d_f[ "first" ] = strInt;
ds.Tables[ "node" ].Rows.InsertAt( d_f, 0 );

DataRow d_s = ds.Tables[ "second" ].NewRow();
d_s[ "myInt0" ] = str_0;
d_s[ "myInt1" ] = str_1;
d_s[ "myInt2" ] = str_2;
ds.Tables[ "second" ].Rows.InsertAt( d_s, 0 );

DataRow d_t = ds.Tables[ "node" ].NewRow();
d_t[ "third" ] = str_T;
ds.Tables[ "node" ].Rows.InsertAt( d_t, 0 );

ds is a DataSet, str_* all of them are string variable not null. I am using a schema, so the order of "first", "second" and "third" is very important for me.

The code does not insert the "node" correctly. :( What should I do in order to correct the problem How to work with such XML files

Thank you!

OK, I solved the problem... ;)

The solution is to use something like that:

_dr.SetParentRow(dr);

Thanks anyway! :)
