how to create Output mapping in wso2 DSS to achieve below structure?

Question

I have created a service in dss and its working. The problem is i am getting output as :

<cir_registryCollection xmlns="http://cts.falcon/cir">
 <cir_getRegistryData>
  <ID>AamProp_721</ID>
  <Description>its really tough to do this</Description>
  <ID>AamProp_721</ID>
  <SourceID>AamPublic_134</SourceID>
  <Description>its really tough to do this</Description>
  <ISO15926ReferenceURI>arya2Publication@books.com</ISO15926ReferenceURI>
  <Registry_ID>Book_112</Registry_ID>
</cir_getRegistryData>
</cir_registryCollection>

but i want my output as :

<cir_registryCollection xmlns="http://cts.falcon/cir">
     <cir_getRegistryData>
      <ID>AamProp_721</ID>
      <Description>its really tough to do this</Description>
</cir_getRegistryData>
<cir_getCategoryData>
<ID>AamProp_721</ID>
      <SourceID>AamPublic_134</SourceID>
      <Description>its really tough to do this</Description>
      <ISO15926ReferenceURI>arya2Publication@books.com</ISO15926ReferenceURI>
      <Registry_ID>Book_112</Registry_ID>
</cir_getCategoryData>
        </cir_registryCollection>

how to achieve this structure using output mapping? looking forward to your answers. Thanks in advance.

The above thing is done but there is a problem? I have my DSS Service as:

<data name="cir_GetAllRegistry_DataService" serviceNamespace="http://cts.falcon/cir">
   <description>select all data from all tables                          &#13;                                &#13;                                &#13;                                &#13;                                &#13;                                &#13;                                </description>
   <config id="Cir_DataSource">
      <property name="carbon_datasource_name">CIR_MySQL_DB</property>
   </config>
   <query id="select_all_cir_table_query" useConfig="Cir_DataSource">
      <sql>select r.ID,r.Description,c.ID,c.SourceID,c.Description,c.ISO15926ReferenceURI,c.Registry_ID from cir_registry r join cir_category c&#13;on r.ID=c.Registry_ID;</sql>
      <result element="Entries" rowName="Entry">
         <element column="ID" name="ID" xsdType="string"/>
         <element column="Description" name="Description" xsdType="string"/>
         <element column="ID" name="ID" xsdType="string"/>
         <element column="SourceID" name="SourceID" xsdType="string"/>
         <element column="Description" name="Description" xsdType="string"/>
         <element column="ISO15926ReferenceURI" name="ISO15926ReferenceURI" xsdType="string"/>
         <element column="Registry_ID" name="Registry_ID" xsdType="string"/>
      </result>
   </query>
   <operation name="select_all_cir_table_operation">
      <description>selects all table data in case of no data passed                              &#13;                                    </description>
      <call-query href="select_all_cir_table_query"/>
   </operation>
</data>

I have the column name ID same for table cir_registry as well as cir_category table. Since both have same name, my value everytime gets overwritten. so how to refrence the column ID of registry and category table uniquely?

In DSS, we have the ability to create complex output elements, that is, we can nest the information with any arbitrary XML structure, check this [1] for more information.
