[xsl] SORT

["Kim Durand" <vsd18 at rediffmail dot com>]

I have a problem, The XMl looks like this.
<programs>
   <time id = 200203040456>
 	<timetext>04:56</timetext>
  </time>

<time id = 2002030632>
 	<timetext>06:32</timetext>
  </time>

<time id = 200203041156>
 	<timetext>11:56</timetext>
  </time>

<time id = 200203040146>
 	<timetext>01:46</timetext>
  </time>

<time id = 200203041856>
 	<timetext>06:56</timetext>
  </time>

<time id = 200203040256>
 	<timetext>02:56</timetext>
  </time>

<time id = 200203021456>
 	<timetext>09:56</timetext>
  </time>
</programs>

My problem is to sort out the times in the increasing order. The 
id in the xml file is arranged in the fashion 
yyyymmddHH(hrs)MM(mnts).I can get the HH from 
substring(./time/@id,9,2). and this is what i want to sort in 
ascending order.
so that i may show the timetext in chronological order. How do i 
do this. Can someone help??
Many Thanks
