Reporting Services :: To Transform XML File While Exporting From SSRS

I have a requirement to transform the XML format of the SSRS report while exporting. I tried with some XSLT to implement this, but not getting desried output. Default XML format of my report is

<?xml version="1.0" encoding="utf-8"?>
<Report xsi:schemaLocation="Test http://reportserver?%2FTest&rs%3AFormat=XML&rc%3ASchema=True" Name="Test" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="Test">
<Tablix1>
<Details_Collection>
<Details Country="India" Sales="1000.0000" />
</Details_Collection>
</Tablix1>
</Report>

Output Needed (Report Tag is removed and the look and feel should be changed as below):

<?xml version="1.0" encoding="utf-8"?>
<Tablix1>
<Details_Collection>
<Details>
< Country>"India"</COuntry>
<Sales>1000.0000</Sales>
</Details>
</Details_Collection>
</Tablix1>
