simple conditional looping

Hello Members,

I want to write a simple loop statement like for($i=1; $i <= 50; $i++) in my 
stylesheet to generate 50 tr (table rows).
I am not sure how I can do this. I tried using <xsl:for-each/> but it just 
loops through the nodes. I cannot specifiy any conditional test like in 
<xsl:if /> .
How can I achieve this? Pl. advice.

Thanks & Regards,
Keyur
