[xsl] Re: unable to dynamically set sort order

[Dimitre Novatchev <dnovatchev@xxxxxxxxx>]

This must be a FAQ!:

All attributes of xsl:sort with the exception of "select" can be specified as AVT-s.

The "select" attribute can be any XPath expression. Certainly, an attempt to put an
XPath expression in a variable and pass this variable as the (complete) value of the
"select: attribute -- this will fail for xsl: sort as in any such attempt in XSLT,
because XPath expressions are not evaluated dynamically.

However, if you need to specify the name of a child element, then you can use an
expression like this:

*[name()=$sortColumn]

Therefore, one possible way to achieve your wanted results is:

<xsl:sort order="{$order}" select="*[name()=$sortColumn]"/>

Cheers,

Hello All:
          I am trying to dynamically set sort order and sort column in my 
XSLT. It seems that I can not use an expression for "order".

<xsl:apply-templates select="Uow">
   <xsl:sort select="$sortColumn" order="$sortOrder"/>
   <xsl:with-param name="from" select="$startRow"/>
   <xsl:with-param name="to" select="$endRow"/>
</xsl:apply-templates>

** $sortColumn and $sortOrder are variables here

Is there any other way I can solve this issue? The reason I need to do this 
is to keep track of users preference between requests when they are 
sorting..

Any ideas or help is really appreciated..

Thanks
