Usage of RTF with Grouping and Count

In my stylesheet, I have a RTF variable which contains
following xml tree.

<val>agwore</val><desc>wore
description</desc><totalquantity></totalquantity>
<val>agwore1</val><desc>wore
description1</desc><totalquantity>6</totalquantity>
<val>agwore3</val><desc>wore
description3</desc><totalquantity>7</totalquantity>
<val>New1</val><desc>New
description</desc><totalquantity> </totalquantity>
<val>agwore1</val><desc>wore
description1</desc><totalquantity>6</totalquantity>
<val>agwore3</val><desc>wore
description3</desc><totalquantity>7</totalquantity>
<val>New2</val><desc>New2
description</desc><totalquantity> </totalquantity>
<val>agwore</val><desc>wore
description1</desc><totalquantity>6</totalquantity>
<val>agwore3</val><desc>wore
description3</desc><totalquantity>7</totalquantity>

If you can see above "agwore" contains "agwore1 and
'agwore3" so its <totalquantity> should be agwore1's
<totalquantity> and <agwore3>'s <totalquantity>.

If you can see "New2", it contains "agwore" and
"agwore3".

So I want to display agwore with total quantity 13 and
New2 with totalquantity 13+7= 20.

I am not able to create a generic tenplate or RTF to
get the total quantity. Can anybody suggest me how to
find a good solution?

regards,
Ranjan
