RE: Calculation of Minimum or Maximum value of an element

Here are four techniques you can use:

1. Use the XPath expression

       A[not(../A &lt; .)]
   which finds all A elements that have no other A whose value is
smaller. This expression has quadratic performance.

2. Sort the list and (using the xx:node-set() extension) select the
first or last in sorted order. This has (n log n) performance.

3. Use a recursive template. This has linear performance.

4. Use a library routine, such as the EXSLT min() function: see
www.exslt.org.

Subject: [xsl] Calculation of Minimum or Maximum value of an element



      Hello,

      Can anyone please tell me how to calculate the minimum or
maximum values of a set of nodes and display them using       XSLT ?
      For e.g if I have
      <A>300</A>
      <A>250</A>
      <A>900</A>
      How can I write a template or a function which 
calculates the least A element value and displays it ???

      Thanx,
      Chitra
