can we create Hierarchy level in XML format output in BI Publisher

I am trying to create a BI publisher report with XML format as output. When i try to generate the report I get data in XML as single level in each group. Is there a way to have XML output to have hierarchy level or sub group xml tabs

Example

<dept>A</dept>

<customer>Arun</customer>

<city>XXXX</city>

<dept>B</dept>
