Sequenced xml-reports

Hi,

I need to create a set of xml-reports in BI Publisher. The final structure of an xml-document should be sequenced.

For instance the final structure of an xml-document must be:

<teg1>

<teg2>

<teg2.1></teg2.1>

<teg2.2></teg2.2>

<teg2.3>

< teg2.3.1>< /teg2.3.1>

< teg2.3.2>< /teg2.3.2>

</teg2.3>

<teg2.4></teg2.4>

</teg2>

<teg3>

<teg3.1>

<teg3.1.1></teg3.1.1>

</teg3.1>

<teg3.2></teg3.2>

<teg3.3>

<teg3.3.1></teg3.3.1>

</teg3.3>

</teg3>

</teg1>

When I try to organize an sql data set of a report in order to achieve an xml-structure as I mentioned above, OBI Publisher moves every group of the set and every link I created to the end of the sequence.
