Re: How to access to a node content randomly in xsl:fo

Hi Cihan,

XPath doesn't have a random() function, so it isn't possible without
using an extension function. Your processor probably has facilities
for either writing your own extension functions or using Java methods
that would enable you to get hold of a random number. You could then
use that random number to access a single node. Read your processor's
documentation to find out what's available for you.

Once you've created a random() function (I'll call it math:random()),
you can get hold of all the answer elements in a random order by
sorting them based on random numbers with:

  <xsl:for-each select="answer">
    <xsl:sort select="math:random()" />
    ...
  </xsl:for-each>

Cheers,

Jeni
