[xsl] Looping a node in XSLT

Hi All,
I have requirement to loop through the node N number of times,
Is there any way I can accomplish in XSLT?

for example
<order>
<orderid>10</orderid>
<prod>
<productid>100</productid >
<productqty>200< productqty>
</prod>
</order>

Desired out put
<order>
<orderid>10</orderid>
<prod>
<productid>100</productid >
<productqty>200< productqty>
</prod>
<prod>
<productid>100</productid >
<productqty>200< productqty>
</prod>
<prod>
<productid>100</productid >
<productqty>200< productqty>
</prod>
... N times
</order>

Thanks,
Senthil
