Dear Team

I get the following collection as the output when querying oracle database
with complex query.

<getMatrixOutputCllection>
<outputVar>
<level_id>1<level_id>
<assignee>jcooper<assignee>
<reg>1000<reg>
<gold>2000<gold>
<sublevel>1<sublevel>
<status>approve<status>
<outputVar>

<outputVar>
<level_id>1<level_id>
<assignee>jcooper<assignee>
<reg>1000<reg>
<gold>2000<gold>
<sublevel>1<sublevel>
<status>reject<status>
<outputVar>

<outputVar>
<level_id>1<level_id>
<assignee>jcooper<assignee>
<reg>1000<reg>
<gold>2000<gold>
<sublevel>2<sublevel>
<status>pending<status>
<outputVar>


<outputVar>
<level_id>1<level_id>
<assignee>jcooper<assignee>
<reg>1000<reg>
<gold>2000<gold>
<sublevel>3<sublevel>
<status>yes<status>
<outputVar>

<outputVar>
<level_id>1<level_id>
<assignee>jcooper<assignee>
<reg>1000<reg>
<gold>2000<gold>
<sublevel>3<sublevel>
<status>no<status>
<outputVar>


<outputVar>
<level_id>2<level_id>
<assignee>jstein<assignee>
<reg>6000<reg>
<gold>4000<gold>
<sublevel>1<sublevel>
<status>go<status>
<outputVar>


<outputVar>
<level_id>2<level_id>
<assignee>jstein<assignee>
<reg>6000<reg>
<gold>4000<gold>
<sublevel>2<sublevel>
<status>proceed<status>
<outputVar>

<outputVar>
<level_id>2<level_id>
<assignee>jstein<assignee>
<reg>6000<reg>
<gold>4000<gold>
<sublevel>2<sublevel>
<status>pending<status>
<outputVar>
<getMatrixOutputCllection>

I need the output should be ordered accordingly the level_id as follows,

<----desired output as follows----->
<level_id>1<level_id>
<assignee>jcooper<assignee>
<reg>1000<reg>
<gold>2000<gold>

<sublevel>1<sublevel>
<status>approve<status>

<sublevel>2<sublevel>
<status>pending<status>

<sublevel>3<sublevel>
<status>yes<status>
<status>no<status>

<level_id>2<level_id>
<assignee>jstein<assignee>
<reg>6000<reg>
<gold>4000<gold>

<sublevel>1<sublevel>
<status>go<status>

<sublevel>2<sublevel>
<status>proceed<status>
<status>pending<status>

<--end--->

NOTE
----
The output will yield more repeat collections according to the table 
values.(i.e)<level_id>1<level_id> may contain more <sublevel> and 
more relative <status> elements.
But the values of <reg>,<gold>and<assignee>will be same for the particular <level_id>.

I am very new to xslt  and i know basics of xslt only.
I tried to achieve the above output via key() function as explained 
in your Mueneuch -2 ( grouping - thread)method. But i get the same 
output as the db output.

I use jdeveloper as designing tool and oracle soa suite 10.1.3.1.0 
as server and xslt version 1.0 ( i dont know whether xslt 2.0 is 
supported in soa server)

So kindly request you to provide solution for the above scenario.


Thanks
