You're not being very clear. I suspect that when you say "random" order
you actually mean "arbitrary" order - i.e. you want to control the
sequence from your stylesheet, rather than having the elements displayed
in an unpredictable sequence.
The simplest way to do this is with something like:
<xsl:apply-templates select="//book[@category='c4']"/>
<xsl:apply-templates select="//book[@category='c2']"/>
<xsl:apply-templates select="//book[@category='c1']"/>
<xsl:apply-templates select="//book[@category='c5']"/>
<xsl:apply-templates select="//book[@category='c3']"/>
Or you could use keys to make it more efficient.
