getting element from step response to the next step request

dear friends ,
i am facing an issue that i have a step output that i will take from it values to the next response

response that i need it from the first step is

<WSInfo>
<WSId>35460</WSId>
<Desc>Worksheet saved 1</Desc>
<Amt>100.000000</Amt>
<WSCode>P</WSCode>
<Financed>Y</Financed>
</WSInfo>


<WSInfo>
<WSId>35461</WSId>
<Desc>Worksheet saved 2</Desc>
<Amt>0.000000</Amt>
<WSCode>S</WSCode>
<Financed>N</Financed>
</WSInfo>





the blue values i needed in the next step request but the next request tags is different from the response


<WorksheetAmtitem2>100</WorksheetAmtitem3>
<Worksheetfinanceditem2>Y</Worksheetfinanceditem3>
<WorksheetDescriptionitem2>Worksheet saved 1</WorksheetDescriptionitem3>
<WorksheetIDitem2>35460</WorksheetIDitem3>


i have to do mapping from the blue value to the green value of the next step request
how could i do that i can simply do it with XSL but it is not supported please advice
