Hi Saurabh,
From the XSL you have written, it seems to me you
are expecting the output to appear as c4 first, then
c6 and then c2.
You are trying to achieve this by *textual ordering
of xsl:when in your XSLT*. But xsl:when will not
evaluate in the order they are written in XSLT. But
instead, a particular *xsl:when will evaluate to true,
when the XML node will pass the test against that
xsl:when*.
When you do xsl:for-each select="//book" , the XSLT
processor will read <book> tags in order c1, c2, c3,
c4, c5 and c6. When the processor encounters <book
category="c2"> , the 3rd xsl:when in your XSLT will
evaluate to true. Similarly, the processor will
process XML elements c4 and c6.
The question still is a bit ambiguous, and answers
till now seem to address the problem asked. If you can
explain more clearly, some body can provide the right
solution.
Regards,
Mukul

Hi,
Thanks for your mail. What you have mentioned about
ascending/descending order that thing I know. If I
write the statement
<xsl:sort select="@category" order="descending"/>
then
ouput will come as category 6, 5 , 4, 3......
For ascending it will come as category c1, c2,
c3.......
But I want to select the category at random order
not
as ascending or descending order. Suppose there are
6
categories in
books.xml file. Now I want to select only 3
categories
in ouput file ( e.g in html) and their position will
be different -
such as 4th (category="c4" in xml doc) will come at
1st position (in html doc), 6th (category="c6" in
xml
doc) will come at
2nd position (in html doc) and 2nd (category="c2" in
xml doc) will come at 3rd position(in html doc).

said what criteria you want to use for
sorting - is it
descending order by category name, or what?
You could get the order c3, c2, c1, by adding
<xsl:sort select="@category" order="descending"/>
immediately after the <xsl:for-each>
You have an xsl:choose with three branches, but
they
are all the same.
This makes it very difficult to understand what
exactly you are trying
to achieve.
